Best for speech features built on Azure
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.
Who Azure AI Speech is for
- Fits if you already build on Azure and want speech in the same bill
- Works for developers who need transcription, translation and speech output from one vendor
Who Azure AI Speech is not for
- Not for you if you want an editor to paste a script into, because it's an API and console service
- Tight if you plan custom voices, since access is limited and training and endpoint hosting cost extra
- Watch out: prices follow the region you pick and are labelled estimates that vary by agreement and currency
- Watch out: the product was renamed to Azure Speech in Foundry Tools, so older docs and tutorials use the earlier name
Why Azure AI Speech gets a 2.2
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyNo 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.
- BFree plan and trialThe 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.
- CFeaturesNeural 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.
- DEase of useNo 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.
- BPlatforms and integrationsWeb and API only, with Microsoft Foundry and Azure OpenAI as the listed hooks. No desktop or phone app.

Keep Azure AI Speech, 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.
What you could not
- A voice model, which you can rent by the minute but not make.
- A voice model trained on your recordings.
- Speech turned into text you can trust.
- It plugs into other products, Microsoft Foundry and Azure OpenAI among them, and has an API.
What this rests on. Azure AI Speech’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
