Question

undefined result with microsoft-cognitiveservices-speech-sdk

Viv 5

We’re using the Node SDK (microsoft-cognitiveservices-speech-sdk) version 1.33.1 (latest) to classify pre-recorded speech input (wav). Following the example code, we’re creating a SpeechRecognizer instance and using recognizeOnceAsync to get the single-shot response from the API before converting it into a PronunciationAssessmentResult. Unfortunately we’re running into an unexpected scenario where the value passed to the recognizeOnceAsync success callback is undefined. This isn’t supported by the types and we aren’t sure what it means or how to handle it.

Thanks for the question, The recognizeOnceAsync method of the SpeechRecognizer class in the Microsoft Cognitive Services Speech SDK is designed to start speech recognition and stop after the first utterance is recognized. The task returns the recognition text as a result.

If the value passed to the recognizeOnceAsync success callback is undefined, it might be due to an error during the recognition process. The SDK provides a way to handle different types of results and errors. Here’s a simplified example:

var result = await recognizer.RecognizeOnceAsync(); // Checks result. if (result.Reason == ResultReason.RecognizedSpeech) { console.log(`RECOGNIZED: Text=${result.Text}`); } else if (result.Reason == ResultReason.NoMatch) { console.log("NOMATCH: Speech could not be recognized."); } else if (result.Reason == ResultReason.Canceled) { var cancellation = CancellationDetails.FromResult(result); console.log(`CANCELED: Reason=${cancellation.Reason}`); if (cancellation.Reason == CancellationReason.Error) { console.log(`CANCELED: ErrorCode=${cancellation.ErrorCode}`); console.log(`CANCELED: ErrorDetails=${cancellation.ErrorDetails}`); console.log("CANCELED: Did you update the subscription info?"); } }

If you’re still encountering issues, it might be helpful to check the error details provided in the cancellation object for more information about what might be causing the undefined value.

Hi, I’m with Viv. If result is undefined, there is no reason value. In fact, trying to access one triggers an exception.

For context, we are using pre-recorded audio and only interested in pronunciation results. If there is a better way of retrieving this please advise.
