Deepgram, a leader in transcription services, shares insights on building effective conversational AI voice agents. The presentation covers critical aspects of implementing voice AI in production, including managing latency requirements (targeting 300ms benchmark), handling end-pointing challenges, ensuring voice quality through proper prosody, and integrating LLMs with speech-to-text and text-to-speech services. The company introduces their new text-to-speech product Aura, designed specifically for conversational AI applications with low latency and natural voice quality.
# Building Production-Ready Voice AI Agents at Deepgram
## Company Overview and Context
Deepgram has established itself as a leader in the transcription space, working with major clients including Spotify and AT&T. The company is expanding its offerings with a new text-to-speech product called Aura, specifically designed for conversational AI applications. This case study examines the technical challenges and solutions in implementing production-ready voice AI agents that combine LLMs with speech technologies.
## Technical Architecture Overview
The basic architecture of a conversational AI voice agent consists of several key components:
- Speech-to-text conversion for user input
- LLM processing for understanding and response generation
- Text-to-speech conversion for system output
- Integration layer managing the flow between components
## Critical Production Challenges and Solutions
### Latency Management
