Not able to get transcript even with audio sent

[zedler]

Hi
I am using python. Just started with first code. I am using fastAPI endpoint and using Deepgram SDK for transcription. Here is the code
I am printing result.channel.alternatives[0].transcript inside onMessage., This is what i am getting.
I checked the data and it is binary as well.
result.channel.alternatives[0].transcript
{
"alternatives": [
{
"transcript": "",
"confidence": 0.0,
"words": []
}
]
}
{
"transcript": "",
"confidence": 0.0,
"words": []
}

router = APIRouter()
deepgram_service = DeepgramService()
config = DeepgramClientOptions(
options={"keepalive": "true"} # Comment this out to see the effect of not using keepalive
)
dgClient = DeepgramClient(settings.DEEPGRAM_API_KEY, config )

@router.websocket("/ws/transcribe")
async def websocket_endpoint(websocket: WebSocket):
await websocket.accept()
try:
# deepgram_socket = await process_audio(websocket)

    dgSocket = dgClient.listen.live.v("1")
    print("Acquired socket object....")
    def on_message(self, result, **kwargs):
        print("Inside On_Message")
        sentence = result.channel.alternatives[0].transcript
        print(result.channel)
        print(result.channel.alternatives[0])
        print(result.channel.alternatives[0].transcript)
         
        if len(sentence) == 0:
            return
        print(f"speaker: {sentence}")
        websocket.send(sentence)

        print(f"\n\n{result}\n\n")

    dgSocket.on(LiveTranscriptionEvents.Metadata, on_metadata)
    dgSocket.on(LiveTranscriptionEvents.Error, on_error)

    print("Registered handlers with socket....")

    if dgSocket.start(options) is False:
        print("Failed to start connection")
        return
    print("Socket connection started....")

    while True:
        data = await websocket.receive_bytes()
        # print("socket data::")
        # print(data)
        dgSocket.send(data)

except Exception as e:
    raise Exception(f'Could not process audio: {e}')
finally:
    await websocket.close()`
