Developer builds free voice AI
Original: How I Built a Free Voice AI Pipeline Using Whisper, LLaMA 3.1 & Groq
Short summary
Developer built VoiceIQ, a free voice AI pipeline using Whisper for speech-to-text, LLaMA 3.1 for reasoning, and gTTS for synthesis with Streamlit UI. Includes conversation memory; prioritizes Groq's fast inference over OpenAI's marginal accuracy gains for voice latency. Full implementation and tradeoff discussion available; author happy to discuss details in comments.
- •Complete voice AI pipeline: Whisper → LLaMA 3.1 → gTTS, orchestrated with Streamlit
- •Zero-cost using Groq free tier; speed-over-accuracy tradeoff justified for voice UX
- •Adds conversation memory; real bug fixes and architectural decisions shared
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
