Fetch "transcript" values from Google speech api - ios

Question

I am trying to fetch the "transcript" value from the following result:
{
transcript: "1 2 3 4"
confidence: 0.902119
words {
start_time {
nanos: 200000000
}
end_time {
nanos: 700000000
}
word: "1"
}
words {
start_time {
nanos: 700000000
}
end_time {
nanos: 900000000
}
word: "2"
}
words {
start_time {
nanos: 900000000
}
end_time {
seconds: 1
}
word: "3"
}
words {
start_time {
seconds: 1
}
end_time {
seconds: 1
nanos: 300000000
}
word: "4"
}
}
The code I am writing to get it is :
for result in response.resultsArray! {
if let result = result as? StreamingRecognitionResult {
for alternative in result.alternativesArray {
if let alternative = alternative as? StreamingRecognitionResult {
textView.text = "\(alternative["transcript"])"
}
}
}
}
So when I am trying to put the value in textview.text I am getting an error stating :
"Type 'StreamingRecognitionResult' has no subscript members ".
Please help.

Answer 1

The key lines are:
let tmpBestResult = (response.resultsArray.firstObject as! StreamingRecognitionResult)
let tmpBestAlternativeOfResult = tmpBestResult.alternativesArray.firstObject as! SpeechRecognitionAlternative
let bestTranscript = tmpBestAlternativeOfResult.transcript
The placement of these lines inside the streamAudioData() is given below:
SpeechRecognitionService.sharedInstance.streamAudioData(audioData,languageCode: self.selectedLangType.rawValue,
completion:
{ [weak self] (response, error) in
guard let strongSelf = self else {
return
}
if let error = error {
debugPrint(">>)) Process_delegate error >> \(error.localizedDescription)")
strongSelf.stopRecordingSpeech()
self?.delegate.conversionDidFail(errorMsg: error.localizedDescription)
} else if let response = response {
var finished = false
debugPrint(response)
for result in response.resultsArray! {
if let result = result as? StreamingRecognitionResult {
if result.isFinal {
finished = true
}
}
}
let tmpBestResult = (response.resultsArray.firstObject as! StreamingRecognitionResult)
let tmpBestAlternativeOfResult = tmpBestResult.alternativesArray.firstObject as! SpeechRecognitionAlternative
let bestTranscript = tmpBestAlternativeOfResult.transcript
strongSelf.delegate.conversionOnProcess(intermediateTranscript: bestTranscript!, isFinal: finished)
if finished {
//UI
strongSelf.stopRecordingSpeech()
strongSelf.delegate.conversionDidFinish(finalTranscript: bestTranscript!)
}
}
})
Happy Coding ;)

Answer 2

So the code will be changed to this:
for alternative in result.alternativesArray {
if let alternative1 = alternative as? SpeechRecognitionAlternative {
textView.text = "\(alternative1.transcript)"
}
}
