- Timeout constraints causing fallbacks to less accurate models
- Configuration issues with language settings
- Speech endpointing problems (detecting start/end of speech)
Here are some troubleshooting steps you might try:
1. Consider switching to the GPT-4o cluster instead of the realtime cluster, as [the realtime cluster is considered unstable by OpenAI](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1337465970557452299)
2. Adjust endpointing settings to give more time for speech processing
3. Check your audio quality and environment settings
If you're still experiencing issues, many users have found success by switching to alternative STT providers such as:
- Deepgram, which offers [high accuracy transcription using end-to-end deep learning models](https://docs.vapi.ai/providers/transcriber/deepgram)
- Talkscriber, which boasts [industry-leading transcription accuracy with a Word Error Rate under 4%](https://docs.vapi.ai/providers/transcriber/talkscriber)Vapi Support Bot
