I am using instant mode in tts stream api, it was expected to give first audio chunk in 200ms, but it is taking about 2 secs, which is much higher...Please find the implementation below async def stream_tts(self, message_text): client = AsyncHumeClient(api_key=HUME_API_KEY) voice_id = "87c85b13-9dab-4b4d-bdd1-70182301d671" utterances = [ PostedUtterance(text = message_text, speed = 1, voice = PostedUtteranceVoiceWithId( id=voice_id, provider="CUSTOM_VOICE") ), ] logging.info (f"Sending TTS request with voice ID: {voice_id}") async for snippet in client.tts.synthesize_json_streaming( utterances=utterances, num_generations=1, split_utterances=False, instant_mode=True, format=FormatWav() ): audio_data = base64.b64decode( snippet.audio ) logging.info (f"Received raw wav snippet of size {len(audio_data)} bytes") Can you please help me improve the latency for this
