Aura relies on state-of-the-art Text-to-Speech (TTS) models to deliver human-like, low-latency audio.
Supported Providers
Seminara uses a multi-provider architecture for maximum reliability and lowest latency:
- Primary Voice Provider: Optimized for ultra-low latency conversational agents. This is the default provider.
- Fallback Voice Provider: Used if the primary provider experiences downtime or if a highly specific emotive voice is required.
Selecting a Voice
In the Aura Customization settings, you can preview the available voices. We provide a curated list of voices optimized for presentations. Currently available voices:
- Female 1 (Thalia) - Female, US
- Male 1 (Orion) - Male, US
Latency Considerations
Our orchestration engine is tuned to achieve 1200ms - 2000ms response times. Voice selection can slightly impact this. Our primary provider generally offers the lowest time-to-first-byte (TTFB), which is critical for making interruptions feel natural.
