I'm currently using the livekit package version 0.18.3 in python and the livekit-plugins-openai package on 0.12.3. I've found the TTS from openAI can suffer from high latency leading to choppy speech. which TTS provider that is integrated with livekit have folks found to provide the best latency figures and TTFB?

Thanks for reaching out, Wolfgang. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Thank you for your question! Based on the available information, two TTS providers integrated with LiveKit that emphasize low latency are: • Speechify: Offers ultra-low latency, human-quality text-to-speech API with voice cloning features. • Cartesia: Produces natural-sounding speech with low latency. Both providers are officially integrated with LiveKit and can be used within the LiveKit Agents framework. While both are noted for their low latency, specific metrics like Time To First Byte (TTFB) are not directly compared in the available resources. You may want to test both to determine which best meets your needs. Sources: Speechify TTS integration guide | LiveKit Docs | Cartesia integration guide | LiveKit Docs
