Vapi voice agent with AssemblyAI Universal-3 Pro Streaming

Vapi's integration with AssemblyAI's Universal-3 Pro Streaming offers advanced speech-to-text capabilities for voice agents, providing features such as punctuation-based turn detection, keyterm prompting, and a low latency of 307ms P50. This integration simplifies the process for users by handling telephony, turn-taking, and orchestration, while supporting over 14 speech-to-text providers. Users can easily set up the AssemblyAI engine by adding their API key to Vapi's dashboard and configuring it through the creation of an assistant, either via the dashboard or API. The system supports a range of languages, including English, Spanish, French, German, Italian, and Portuguese, and is particularly advantageous for scenarios requiring fast streaming latency, medical terminology recognition, interruption handling, and interactions with multilingual callers. Keyterm prompting enhances accuracy for domain-specific vocabulary, and the setup process is quick, requiring no assistant restart for changes to take effect.
