What we talked about
Raj explains why a polished voice-agent demo is not proof of a useful product. The conversation covers problem validation, real-user testing, accents, multilingual speech, low-latency transcription, consent, voice cloning, AI disclosure, fraud risks and responsible deployment.
Key takeaways
- 01Start with a real problem and test the hypothesis before building a voice agent.
- 02Test the accents, languages, pace and emotional context the agent will meet in production.
- 03Speech-to-text is an engine inside a wider product, not the complete solution.
- 04Voice agents should identify themselves clearly.
- 05Consent, security and human oversight matter because cloned voices can enable fraud.
“You've got to have a problem to solve out there in the first place.”
