I understand your frustration! 😔 Based on the documentation I've found, here are some Voice AI alternatives you might consider:
Retell AI - Some users have reported better performance with Retell AI compared to VAPI, even when using the same LLM (GPT-4) and prompt setup on both platforms [Discord user feedback](https://discord.com/channels/1211482211119796234/1211483291191083018/1336989548357353524).
Other alternatives include:
* ElevenLabs - Known for contextual awareness in speech synthesis and enhanced voice modulation
* PlayHT - Offers conversational voices and flexibility
* Azure Voice Services - Provides reliable TTS services
* Deepgram - Strong speech-to-text capabilities
* Voiceflow - Helps teams build and manage conversational AI agents
Several users have reported issues with VAPI similar to what you're experiencing, including LLM failures and service problems, which led them to explore alternatives.
Is there a specific feature or capability you're looking for in an alternative platform?
