Venky Balasubramanian describes the voice-agent pipeline and the tension between latency, cost and model capability. Model intelligence alone does not ensure dependable instruction following or tool use, while open models bring their own deployment and sizing tradeoffs.
Venky Balasubramanian treats transcription as a brittle input, especially for names, digits and code-switched language. State-specific keywords and controlled normalization can help, but uncertain collected information still needs validation and explicit confirmation rather than invented corrections.
Venky Balasubramanian advocates typed fields for information such as phone numbers and dates, field-level tests and context that follows the call state. A normalization layer prepares generated text for speech with pronunciation dictionaries and careful articulation of important entities. Turn-taking and interruption are raised briefly at the end, not presented as fully demonstrated solutions.
