Azure Speech, now branded Azure Speech in Foundry Tools, is a Microsoft cloud service covering speech to text, text to speech, speech translation and avatars. Its text-to-speech side offers prebuilt Neural and Neural HD voices plus custom and personal voice options. It is billed through an Azure account, with a small free monthly allowance. - **Category:** AI Voices & Text to Speech - **Made by:** Microsoft - **Website:** https://azure.microsoft.com/en-us/products/ai-foundry/tools/speech - **Runs on:** Web - **Who should skip it:** Not for you if you want an editor to paste a script into, because it's an API and console service. - **Facts last checked:** Nov 12, 2026 ## Pricing As of Nov 12, 2026, Azure AI Speech has a free plan. - **Pricing model:** Free plan - **Free plan:** Free (F0) tier: 0.5 million Neural text-to-speech characters per month, plus 5 hours of standard speech to text. - **Free trial:** None listed. | Plan | Price | What you get | | --- | --- | --- | | Free (F0) | $0 | 0.5M Neural characters a month for text to speech, 5 audio hours for speech to text and translation. | Read from https://azure.microsoft.com/en-us/pricing/details/speech/ on Nov 12, 2026. Prices change, so confirm with Azure AI Speech before buying. ## Key features - **Neural and Neural HD voices:** Prebuilt text-to-speech voices come in Neural and Neural HD variants, plus a MAI-Voice model priced alongside them. - **Custom and personal voice:** Professional custom voices are trained and hosted on Azure. Personal voice has free voice creation. Custom voice is a limited-access feature. - **Speech to text and translation:** The same service transcribes calls and meetings and translates speech, with captioning in more than 100 languages. - **Avatars:** Text-to-speech avatars (standard, photo and video) are billed per minute as an add-on to speech synthesis. - **Voice Live API:** A real-time voice agent API billed per million tokens, with pricing tiers set by the underlying language model. ## Good for - Developers building voice features on Azure - Enterprises that need custom brand voices under Microsoft's terms - Projects mixing transcription, translation and speech output ## Worth knowing - Prices follow the region picked on the pricing page; Neural is about $15 per 1M characters and Neural HD about $22 in the US regions. - Custom voice is limited-access, and training and endpoint hosting are charged separately on top of synthesis. - Prices are described as estimates and can vary with the agreement type and currency. - The product was renamed from Azure AI Speech to Azure Speech in Foundry Tools; older docs and tutorials use the earlier name. ## ToolGPA grades **GPA: 2.2 out of 4**, graded Nov 12, 2026. Azure AI Speech is Microsoft's speech API: text to speech, transcription and translation under one Azure account. It gives 0.5 million Neural characters a month free. But it is for developers, bills per character at about $15 per million on Neural, and custom voices are a limited-access feature with training and hosting charged on top. - **Value for money: C.** No flat plan. Neural voices run about $15 per 1M characters and Neural HD about $22 in US regions, so what you pay depends on volume and region. The free allowance is the only thing that brings it down. - **Free plan and trial: B.** The F0 tier gives 0.5M Neural characters a month plus 5 hours of speech to text, free. It sits behind an Azure account, so you set that up first. - **Features: C.** Neural and Neural HD voices, custom and personal voice, transcription, translation, avatars and a real-time voice API. That's the job and then some, but custom voice is limited-access and training and hosting are billed separately. - **Ease of use: D.** No store rating on record, and it's an API and console service. You write code or wire it into other Azure pieces, so this is not a start-typing tool. - **Platforms and integrations: B.** Web and API only, with Microsoft Foundry and Azure OpenAI as the listed hooks. No desktop or phone app. These are ToolGPA's own grades. Graded from this listing, whose facts were read from Microsoft's own pages on 12 November 2026.

The category's chart of price against score: https://toolgpa.com/charts/ai-voices ## Keep it, or make your own? **Keep it.** To replace Azure AI Speech you would be making a voice model, which you can rent by the minute but not make. That is not a weekend's work, with an AI app builder or without one. - You could not: A voice model, which you can rent by the minute but not make. - You could not: A voice model trained on your recordings. - You could not: Speech turned into text you can trust. - You could not: It plugs into other products, Microsoft Foundry and Azure OpenAI among them, and has an API. A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it. ## Works with Microsoft Foundry, Azure OpenAI **Tags:** Text to speech, Voice cloning, Transcription, Public API ## Alternatives - [Google Cloud Text-to-Speech](https://toolgpa.com/tools/google-cloud-text-to-speech): Pay-per-character speech API with Gemini, Chirp and WaveNet voices.
