Polly allows the use of SSML tags which is great, but I cannot seem to find a tag that would add some kinds emotion. Let's refer to this as Emotional TTS. For instance, the following snippet:
<speak> Hi! My name is Joshua. </speak>
<speak> Hoi! Mijn naam is Lotte. <break time="3s" /> Ik lees elke tekst voor die je hier invoert. </speak>
Is it possible to do Emotional TTS with Polly; e.g. "aaaws" and "aaahs" with Polly? I guess if it were, it would have to be via SSML. Right? How would I modify the above to facilitate such a thing?
If you are using Alexa, depending on language, you might be able to achieve some of this with speechcons:
<speak>
Not quite "aah", but almost:
<say-as interpret-as="interjection">argh</say-as>.
</speak>
See the supported list of speechcons and more details on:
https://developer.amazon.com/en-GB/docs/alexa/custom-skills/speechcon-reference-interjections-english-us.html
Unfortunately, Amazon Polly does not support interjections as of August 2021. You can try it interactively in the browser with the code above, which gives me:
The input you provided isn't valid. Check the input, and then try again.

I have been using the following URL for the past 3 years without issue. However, it has stopped returning results.
URL:
https://query.yahooapis.com/v1/public/yql?q=select * from yahoo.finance.xchange where pair in ("ARSARS")&env=store://datatables.org/alltableswithkeys
Now returns the following:
<?xml version="1.0" encoding="UTF-8"?>
<query xmlns:yahoo="http://www.yahooapis.com/v1/base.rng" yahoo:count="0" yahoo:created="2017-11-02T09:33:25Z" yahoo:lang="en-AU">
<results/>
</query><!-- total: 9 -->
Notice how there are no results, it simply has the tag "results".
I have tried on this many different computers and browsers. I have also tried changing the currency combinations, but no luck.
Can anybody spot what I am doing wrong?
Yes, it looks like Yahoo has discontinued their Currency Converter API service.
I found a different site : https://currencylayer.com/
They let you request currency rates (1 USD = 168 other currencies). If you make less than 1000 requests per month, it is free (if you need more, they have different subscriptions : https://currencylayer.com/product).
You just need to sign up and receive your own Access Code. Once you have that, then you simply make the call http://apilayer.net/api/live?access_key= and it will return JSON of the other currency rates.
They also have code examples in PHP, JavaScript, and Java at https://currencylayer.com/documentation
Found it very easy to get started using their API right away.
I think the API is down.
I am similarly receiving "results"=nullfor the query:
http://query.yahooapis.com/v1/public/yql?q=select+%2A+from+yahoo.finance.xchange+where+pair+in+%28%22GBPEUR%22%29&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys
Setting diagnostics=true in the request yields:
`
[execution-start-time] => 7
[execution-stop-time] => 12
[execution-time] => 5
[http-status-code] => 999
[http-status-message] => Request denied
[content] => http://download.finance.yahoo.com/d/quotes.csv?s=GBPEUR=X&f=snl1d1t1ab
`
If anyone knows more than me about what this might imply I'd be glad to hear it!
Yahoo is aware of this issue and their engineers are working on it:
ref: https://forums.yahoo.net/t5/Yahoo-Finance-help/http-download-finance-yahoo-com-d-quotes-csv-s-GOOG-amp-f/td-p/387096
Very sadly and quite outrageously Yahoo decided to stop this service without any warning.
See admin message here
So many services depend on it, it's like Google saying they would suddenly stop their maps API... At this point I am blocking yahoo in our DNS so no one in our company will ever use Yahoo again since they are not a reliable entity.
1) Given my email, produced via a mailchimp online editor.
2) I go to my openEdX, log in as administrator of the MOOC. Then got to My MOOC > INSTRUCTOR > EMAILS, in order to send my email. First a test to myself, later to my 2000 mooc students.
3) The email I receive in my inbox is CUT HALF WAY. The bottom part is all missing.
QUESTION : What is going on there ? How to fix this ?
Look into your code for the first paragraph which disapeared. It's likely the buggy part.
For this case, I can see the first disappeared sentence is :
💡 Astuce : Pensez à inviter NudiMooc à suivre votre BLOG
My eyes are catched up by the strange 💡 sign, which is a rare unicode character.
Delete this exotic 💡 sign from your email / html5 code, and it will work again. I tested it by sending to myself. Horray ! The corrected code without the lightbulb was complete !! :D
OpenEdX processing may crash on this string. But because there are some witty security, the previous, valid text is kept.
I have an example design in system generator for image processing which has one input image and one output image.
I would like to send data through AXI stream interface and export it as an IP core to Vivado IP integrator and develop the design further using DMA and software in SDK.
Firstly is it possible to have AXI stream interface in my design? If yes, how can I implement it? Can anybody help me?
Thanks in advance.
(i have attached image of the example here)
Image_filter
Firstly is it possible to have AXI stream interface in my design?
Yes, it is.
If yes, how can I implement it? Can anybody help me?
I have a similar project develop in Vivado 2015.3: an image filter (created with "High Level Synthesis") and this design block:
The High Level Synthesis code should look like:
#include "top.h"
void hls_sobel(
hls::stream< ap_axiu<8,1,1,1> > &video_in,
hls::stream< ap_axiu<8,1,1,1> > &video_out
)
{
ap_uint<16> Image_w=IMAGE_W_MAX;
ap_uint<16> Image_h=IMAGE_H_MAX;
// Create AXI streaming interfaces for the core
#pragma HLS INTERFACE axis port=video_in bundle=video_in
#pragma HLS INTERFACE axis port=video_out bundle=video_out
// No control interface - auto-start as soon as there's an input frame
#pragma HLS INTERFACE ap_ctrl_none port=return // no handshakes
hls::Mat<IMAGE_H_MAX, IMAGE_W_MAX, HLS_8UC1> mat_in(Image_h, Image_w);
hls::Mat<IMAGE_H_MAX, IMAGE_W_MAX, HLS_8UC1> mat_out(Image_h, Image_w);
hls::Mat<IMAGE_H_MAX, IMAGE_W_MAX, HLS_8UC1> inx(Image_h, Image_w);
hls::Mat<IMAGE_H_MAX, IMAGE_W_MAX, HLS_8UC1> iny(Image_h, Image_w);
hls::Mat<IMAGE_H_MAX, IMAGE_W_MAX, HLS_16SC1> sobelx(Image_h, Image_w);
hls::Mat<IMAGE_H_MAX, IMAGE_W_MAX, HLS_16SC1> sobely(Image_h, Image_w);
hls::Mat<IMAGE_H_MAX, IMAGE_W_MAX, HLS_16SC1> zerox(Image_h, Image_w);
hls::Mat<IMAGE_H_MAX, IMAGE_W_MAX, HLS_16SC1> zeroy(Image_h, Image_w);
hls::Mat<IMAGE_H_MAX, IMAGE_W_MAX, HLS_8UC1> absx(Image_h, Image_w);
hls::Mat<IMAGE_H_MAX, IMAGE_W_MAX, HLS_8UC1> absy(Image_h, Image_w);
#pragma HLS dataflow
// read input and convert from axi-stream to Mat
hls::AXIvideo2Mat(video_in, mat_in);
// calculate Sobel in X and Y directions
hls::Duplicate(mat_in, inx, iny);
hls::Sobel<1,0,3>(inx, sobelx);
hls::Sobel<0,1,3>(iny, sobely);
// calculate abs of said Sobel
hls::Zero(zerox);
hls::Zero(zeroy);
hls::AbsDiff(sobelx, zerox, absx);
hls::AbsDiff(sobely, zeroy, absy);
// add both abs
hls::AddWeighted(absx, 1, absy, 1, 0, mat_out);
// write output
hls::Mat2AXIvideo(mat_out, video_out);
}
As you can note, a DMA is used. For the Video-Image application, I recommend using a Video-DMA (VDMA) to send all the pixel information via streaming-interface. After, in the SDK, it is easy to manage the transfer using the function in the Board Support Package (BSP).
Also, you can note that in the code above is explicitly specified hls::stream< ap_axiu<8,1,1,1> > &video_in,! In this way, I am creating a streaming interface.
Here you can find a tutorial about HLS image processing filter. In the last page, there are useful links. Follow them to realize the same system of the example.
I hope this can help
I am currently working on a very similar project, (I am not using System Generator though), so I bet I could give you some pointers. As far as I remember SysGen can produce some VHDL or Verilog code of your design. So:
After you get the HDL code of your design, pack it as a new IP in Vivado. There are plenty of tutorials on how to do this, it should be easy with a little search. You should wisely choose the interfaces you want to implement. You're going to definitely need an AXI Stream Slave interface for accepting the incoming data and an AXI Stream Master interface to transmit the results.
After you package your IP, you can begin building your system block-by-block (there are also some good tutorials on this, see end of answer). You will need to use the AXI DMA IP (or the Video DMA, depending on your needs) and you'll have to configure it properly, like choosing register-mode or scatter-gather, channels, etc.
Be extremely careful to generate the proper AXI synchronization signals correctly, as they can totally ruin your design (and nerves). It's easy but it requires some study of the AXI documentation provided by Xilinx (ARM's docs are too complicated for my taste).
Finally, you will definitely find very useful information on the following resources:
Xilinx Forum
FPGAdeveloper's example
another AXI-stream based design example
FPGA note wiki
AXI DMA Product Guide
Channel of Dr. Sadri of TU Kaiserslautern, really helpful to deeply understand AXI design concepts
Good luck!
PS: Simulators are your friends! Never try implementing your freshly written code directly onto the system design. Modelsim can save you significant time and effort which would otherwise be spent on pointless debugging.
If I understand correctly, you want to know how to create an AXI Stream interface inside your system generator design.
Yes it is possible to do it. You should have atleast two inputs in your design with names, for example, image_tdata and image_tvalid (gateway in). When you generate IP core, sysgen will recoginize this as an AXI STREAM. The format is important. It must be "$customname_tdata" and "$customname_tvalid". You can add other inputs as well to add to the AXI STREAM such as "$customname_tlast", "$customname_tready".
How do I capture all the packets in radio range of a particular node in contiki?
While reading the contiki mailing lists and contiki github, I could read people saying something about making changes to core/dev/cc2420.c file. Some people spoke about setting or resetting values of CC2420_CONF_AUTOACK.
I nowhere found proper information regarding putting a node in promiscous mode. Please help.
I guess what you mean to do is to disable the hardware address filtering. There is a radio API for this in Contiki:
#include "dev/radio.h"
// ...
radio_value_t radio_rx_mode;
if(NETSTACK_RADIO.get_value(RADIO_PARAM_RX_MODE, &radio_rx_mode) == RADIO_RESULT_OK) {
radio_rx_mode &= ~RADIO_RX_MODE_ADDRESS_FILTER;
NETSTACK_RADIO.set_value(RADIO_PARAM_RX_MODE, radio_rx_mode);
}
You can also disable automatic acknowledgements by removing the RADIO_RX_MODE_AUTOACK bit of the rx_mode, but that's a different setting.
I was wondering if you know of any way to use prolog for stream processing, that is, some kind of reactive programming, or at least to let a query run on a knowledge base that is continuously updated (effectively a stream), and continuously output the output of the reasoning?
Anything implemented in the popular "prologs", such as SWI-prolog?
You can use Logtalk's support for event-driven programming to define monitors that watch for knowledge base update events and react accordingly. You can run Logtalk using most Prolog systems as the backed compiler, including SWI-Prolog.
The event-driven features are described e.g. in the user manual:
http://logtalk.org/manuals/userman/events.html
The current distribution contains some examples of using events and monitors. An interesting one considering your question is the bricks example:
https://github.com/LogtalkDotOrg/logtalk3/tree/master/examples/bricks
Running this example first and then looking at its code should give you as good idea of what you can do with system wide events and monitors.
XSB has stream processing capabilities. See page 14 in the
XSB Manual
I'm working on something related, in project pqConsole already there is the basic capability: report to the user structured data, containing actionable areas (links) that call back in Prolog current state, hence the possibility to expose actions and react appropriately (hopefully).
It's strictly related to pqConsole::win_write_html, showcasing recent Qt capabilities of SWI-Prolog.
Here an example of a snippet producing only a simple formatted report, I'll try now to add the reactive part, so you can evaluate if you find expressive this basic system. Hints are welcome...

and now the file names are clickable, write a message and get edited if requested: a picture
You should check out RTEC: Run-Time Event Calculus:
https://github.com/aartikis/RTEC
RTEC is an open-source Event Calculus dialect optimised for stream reasoning. It is written in Prolog and has been tested under YAP 6.2.
Feature highlights:
Interval-based.
Sliding window reasoning.
Interval manipulation constructs for non-inertial fluents.
Caching for hierarchical knowledge bases.
Support for out-of-order data streams.
Indexing for handling efficiently irrelevant data.
There is also a mention of it on the SWI-Prolog website:
https://www.swi-prolog.org/pack/file_details/prologmud_I7/prolog/ec_planner/RTEC/README.md
which presumably relies on:
https://www.swi-prolog.org/pldoc/doc/_SWI_/library/dialect/yap.pl
I don't know why this hasn't been brought up so far, but in SWI-Prolog there is prolog_listen, which can, amongst other things, monitor dynamic updates to the database:
