I will develop a voice AI assistant with speech recognition and text to speech

About this service

Want users to talk to your product instead of typing? I build voice AI assistants combining speech-to-text, LLM reasoning, and natural text-to-speech for phone, web, or app experiences.

  • Speech recognition (Whisper, Deepgram) tuned for your accents and terms
  • LLM-driven conversation logic and intent handling
  • Natural voice output with ElevenLabs or cloud TTS
  • Low-latency streaming for real-time conversation feel
  • Phone (Twilio), web, or mobile integration

I've built voice bots for appointment booking, support, and IVR replacement. I focus on latency and naturalness so conversations feel human, not robotic.

Describe the voice experience you want and I'll recommend the right stack and realistic latency. Let's give your product a voice your users will actually enjoy talking to.
