Deepgram's Aura-2 is a text-to-speech (TTS) model, which is an AI that reads written text out loud in a human-sounding voice. It is made for businesses and developers who need to build things like customer service phone bots, reading apps, or AI assistants that can talk back to users the second they are prompted.
What it does well
- Real-time speed: It is "purpose-built for realtime enterprise use cases," meaning it is designed to speak instantly without making the user wait for the audio to load.
- Enterprise focus: It is tailored for heavy-duty business applications, so it is meant to be reliable when handling lots of requests at once.
