How to use voice-to-text service with voip phone calls?

Question by FQian (1) | Oct 26, 2016 at 04:45 PM watson speech-to-text

Hello,

We are trying to use voice-to-text service to transcribe incoming call from a phone. The call is picked up by a virtual softphone and the analogue signal is digitized using PCM. Then the data packet is send to Watson voice-to-text to be converted with a narrow band mode used. However, often times we don't get any script output. Are we missing something here?

Thanks for you help in advance.

Do you have a control in your sample test usage. IE. Are you capturing the audio to verify what has been captured?

Hello @FQian can you provide more details on what is going on? Are you using the REST or the WebSocket interface?

please make sure you use the flag continuous=true for continuous recognition. Otherwise the recognition will stop after the first utterance.

@chughts and @Daniel Bolanos, thanks for your reply. We use WebSocket. Here's the specific piece of code we used. After turned the flag continuous=true, we are still not getting output text. alt text

Hi @FQian are you using the Java SDK?

Have you tried with the examples provided?

https://github.com/watson-developer-cloud/java-sdk/blob/master/tests/src/test/java/com/ibm/watson/developer_cloud/speech_to_text/v1/SpeechToTextIT.java

If that does not work for you, please open an issue in that repo.
