To address the issue of distorted voice at the end of sentences with the Deepgram text-to-speech model, here are some steps you can take:
•
Check TTS Configuration: Ensure the model, encoding, and sample rate are properly configured. For example:`tts = deepgram.TTS( model="aura-2-andromeda-en", encoding="linear16", sample_rate=24000 )`
•
Use SSML Tags: Add pauses or adjust prosody at sentence boundaries using SSML. For example:`text = "Hello, how are you?" await session.say(text)`
•
Handle Text Chunking: Ensure that text is processed correctly to avoid issues at sentence boundaries. Avoid unnecessary splitting of text into chunks.
•
Test with Custom Pronunciation: If specific words cause distortion, use SSML or phoneme tags to define pronunciation.
•
Verify Audio Handling: Ensure the audio stream is properly buffered and handled on the client side.
If the issue persists, could you provide more details such as:
• Are you using a specific Deepgram TTS model?
• Does the distortion occur consistently with certain sentences?
• Are you applying any custom text processing or SSML tags?
• Have you tried different audio encodings or sample rates?
This information will help narrow down the cause and suggest more targeted solutions.
