What we know about Deepgram Aura-2

Deepgram Aura-2 sits in the text-to-speech apis category, where it is enterprise real-time voice-agent TTS. We keep this Deepgram Aura-2 profile grounded in primary sources, each fact dated to when we last confirmed it.

Deepgram Aura-2 does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current Deepgram Aura-2 quote, it is the fastest way for us to close that gap.

On capabilities, Deepgram Aura-2 covers streaming audio output, realtime websocket api, commercial use on free tier, soc 2 type ii, and self-host / on-prem option, and does not offer instant voice cloning, professional voice cloning, and ssml support. Each of those is verified against Deepgram Aura-2's own docs or dashboard, not marketing copy.

For compliance, with Deepgram Aura-2: SOC 2 Type II is in place. If you are in a regulated space, confirm the current posture with Deepgram Aura-2 before you commit, since these change plan by plan.

Deepgram Aura-2 ranks the 4th-cheapest fast-model rate of the 10 text-to-speech tools we track, but only 33rd of 10 for languages, so where it lands for you depends on which of those matters more.

STT in this stack

Text-to-speech is half of a voice pipeline: the other half is the speech-to-text that listens. Compare transcription engines on accuracy, streaming latency, and per-minute price: Deepgram, AssemblyAI, GPT-4o Transcribe, or the full speech-to-text comparison →

Voice agents in this stack

The same vendor runs this engine as a full agent platform: see Deepgram Voice Agent API for the end-to-end per-minute cost. Or compare the platforms builders wire Deepgram Aura-2 into: Pipecat, OpenAI Realtime API, Twilio ConversationRelay, or the full voice-agent comparison →

Distribute it

Most Deepgram Aura-2 voiceover ends up in short-form video, and publishing that video across TikTok, YouTube, and Instagram is a scheduling problem with real per-channel pricing. Compare the schedulers creators actually run: Buffer, Postiz, Mixpost, or the social media scheduling platforms compared →

Avatar video in this stack

A cloned or bring-your-own Deepgram Aura-2 voice does not have to stay audio-only: AI avatar video platforms lip-sync it onto a talking avatar for finished video. Compare the platforms: HeyGen, Synthesia, Hedra, or the full avatar-video comparison →
