### Answer Based on the available sources, real-time PCM audio bytes and real-time transcription events are documented specifically for web calls using the Retell Web SDK. [(1) ]() For web calls, you can listen to events like: -

audio

event for real-time PCM audio bytes (when

emitRawAudioSamples

is set to

true

) -

update

event for real-time transcript updates

javascript
retellWebClient.on("audio", (audio) => {
  // console.log(audio) ;
}) ;

retellWebClient.on("update", (update) => {
  // console.log(update) ;
}) ;

However, I don't have documentation in the available sources that confirms whether equivalent real-time audio streaming and live transcription monitoring is available for phone calls via the API. The phone call documentation shows post-call data (transcripts, recordings) but doesn't explicitly describe real-time monitoring capabilities during live phone calls. [(2) ]() Check out these potentially useful sources: - [Register Phone Call]() - [Connect to web call]() - [Update Voice Agent]() Would you like me to provide a general answer based on my knowledge, or would you prefer to reach out to Retell support directly for confirmation on phone call monitoring capabilities?
