What is Speech Studio?

Speech Studio is a natural text to speech tool. Microsoft's portal for turning text into natural speech, with 150+ voices across 500 languages, custom voice training, personal voice cloning and talking avatars, backed by Azure Speech documentation and SDK samples.

Speech Studio is Microsoft's browser-based workspace for building voice into applications. It sits on top of Azure AI Speech and gathers the text to speech capability in one place, alongside speech to text, translation, voice assistants and avatars. The text to speech side is the core offer: the platform advertises more than 150 voices across 500 languages and dialects, with multiple speaking styles intended to carry emotion and pacing rather than flat narration. For teams that need a branded sound, the studio provides two paths. Professional voice fine-tuning uses your own audio recordings to train a distinct voice, while Personal Voice creates an AI voice from a human voice sample and applies it across 100 languages. A Voice Gallery lets you audition expressive, humanlike speakers before committing to one, and Audio Content Creation gives hands-on control over speaking style, pacing and pronunciation for recorded material. A text to speech Avatar goes further by pairing synthesized speech with a photorealistic talking face. The tool is clearly built for developers and product teams rather than casual writers. Several capabilities are framed as try-it experiences with sample code, and the surrounding resources point to SDK quick starts on GitHub, documentation and the Microsoft Learn training paths. Audio and localization teams also fit here, particularly through video translation, which dubs video across more than 100 languages using either the prebuilt voice library or a personal voice. Compared with lighter text to speech web apps, Speech Studio trades simplicity for depth: custom model training, avatar output, keyword creation and pronunciation assessment are available in the same portal. That breadth comes with the usual Microsoft platform overhead, and Microsoft states that its speech tools are now also reachable through Azure AI Foundry. Responsible AI guidance covering fairness, transparency and privacy is published on the same page.

How do you use Speech Studio?

  1. 1Open the Speech Studio portal
    Go to the portal in a browser to see the scenario overview, including text to speech, speech to text, avatars and translation. Each scenario links to a hands-on try-it experience.

  3. 3Control delivery with Audio Content Creation
    Start an Audio Content Creation project to adjust speaking style, pacing and pronunciation so the spoken output matches the tone you want.
  4. 4Train a custom or personal voice
    Begin a Professional voice fine-tuning project with your own recordings for a distinct brand voice, or try Personal Voice to build an AI voice from a human voice sample for use across 100 languages.
  5. 5Wire speech into your application
    Move from experimentation to code using the documentation and the SDK quick start samples published on GitHub, which cover a range of languages and platforms.

Pros and cons
