What is Voice AI?
The technical architecture of enterprise voice AI has several distinct latency-critical components. Automatic Speech Recognition (ASR) must transcribe customer speech in real time, detecting end-of-utterance quickly to enable responsive turn-taking. The transcribed text goes to the language model for intent understanding and response generation — a pipeline that must complete in under 500ms to maintain conversational naturalness. Text-to-Speech (TTS) must produce natural, brand-consistent speech in the customer's language. End-to-end latency — from customer finishing speaking to AI starting to reply — below 800ms is the threshold for natural-feeling conversation. Above 1.5 seconds, conversations feel broken.
Enterprise voice AI deployments have unique requirements beyond consumer voice assistants. Telephony integration: connecting to enterprise call center infrastructure (Genesys, Avaya, Cisco, NICE), handling DTMF tones, managing call transfers to human agents, and recording compliance-grade call summaries. Concurrent call handling: unlike a single-session chatbot, an enterprise voice AI must handle hundreds to thousands of simultaneous calls with consistent quality. Interruption handling: customers in telephone calls interrupt more than in text conversations; voice AI must detect barge-in (customer speaking while AI is speaking), pause gracefully, and process the new input. Multilingual in a single call: code-switching (moving between Hindi and English mid-conversation) is common in Indian enterprise contexts and must be handled natively.

Key Points
Core idea
End-to-end latency below 800ms makes voice AI feel like talking to a person. Above 1.5 seconds, the conversation feels broken. Every component — ASR, LLM, TTS — must be optimised for this budget.
Why it matters
Enterprise voice AI must integrate with existing call center infrastructure, manage call recording and compliance, handle transfers to human agents with full context, and generate call summaries for CRM.
Enterprise use
An enterprise voice AI handling customer service for a major bank or insurer must support hundreds to thousands of simultaneous calls. Inference infrastructure must scale horizontally without latency degradation.
How Voice AI works
Define the purpose, inputs, and success criteria that Voice AI must support.
Apply Voice AI in the relevant workflow while recording its inputs, configuration, and outputs.
Evaluate the result against representative data, operational constraints, and human review before expanding production use.
