Second initialization of LiveTranscription doesn't send data to deepgram

[tipu]

What is the current behavior?

I have an interaction with a stream of audio that should be transcripted. It's not like a podcast where it is a single large stream, rather it's more conversational where there could be a sentence and a pause of 30 seconds or more and then another sentence. I figure the best thing to do is use a unique instance for each interaction.

The problem is that subsequent instances of the LiveTranscription object don't seem to send data. The first time through the code it works fine but when deepgramLive is initialized a second time, the TRANSCRIPT_RECEIVED handler is never fired until eventually it closes, that is, the CLOSE handler is called.

One thing to note is if I don't reinitialize deepgramLive, the stream can pick up subsequent phrases.

Steps to reproduce

@app.websocket("/ws/test")
async def test(websocket: WebSocket):
    await websocket.accept()
    async def receive_deepgram_transcript(msg):
        nonlocal transcript
        if msg.get("is_final"):
            transcript = (
                msg.get("channel", {})
                .get("alternatives", [{}])[0]
                .get("transcript", "")
            )
            if transcript != "":
                print(transcript)

    deepgramLive = None
    transcript = None
    while True:
        while not transcript:
            if not deepgramLive:
                deepgramLive = await dg_client.transcription.live({ 'punctuate': True, 'interim_results': False, 'language': 'en-US' })
                deepgramLive.registerHandler(deepgramLive.event.CLOSE, lambda c: print(f'Connection closed with code {c}.'))
                deepgramLive.registerHandler(deepgramLive.event.TRANSCRIPT_RECEIVED, receive_deepgram_transcript)
            data = await websocket.receive()
            deepgramLive.send(data['bytes'])
        else:
            print("closing")
            await deepgramLive.finish()
            deepgramLive = None

I ended up resolving this using a raw websocket and spamming the KeepAlive message every 5 seconds.

The live client is getting reworked to include the KeepAlive message. Please check back when the PR is merged.

A new release was just posted which should address this problem, please take a look:

The alpha.5 release is out. Have you been able to try this out?
