### Answer Based on the available sources, when you encounter 11labs TTS errors causing repeated speech or pauses, the recommended solution is to switch to another TTS provider [(1) ]() . If you're experiencing poor agent naturalness issues related to TTS, you can take these steps : - **Change voice**: Custom-cloned voices tend to have more naturalness issues; switching to a platform voice often improves stability - **Switch voice provider**: Different providers have different strengths (e.g., naturalness vs. specific languages or accents) Additionally, you can monitor TTS latency details in call history and the Get Call API [(2) ]() . If you notice higher-than-usual TTS latency, you can switch to another TTS provider directly . For ongoing TTS issues, I recommend reviewing your call logs for specific error patterns and considering a failover voice configuration to maintain call quality when provider issues occur.
