200+ is NVR's supported promise
Microsoft's broader Speech catalog can contain more voices than NVR chooses to expose. NVR may filter experimental, preview, specialized, regional, higher-cost, or otherwise unsuitable models.
Live Microsoft Azure voice catalog
Hear the Natural Voices before you choose.
Browse Natural Voice Reader's live catalog of supported Microsoft Azure natural neural voices. Filter by language, locale, or voice and press Preview Voice to hear an actual Azure-generated sample. The preview is requested securely through NaturalVoiceReader.net—your browser never receives NVR's Azure credentials.

SECURE PREVIEW DESIGN
Preview buttons do not call Azure directly. The webpage requests a controlled preview from the NVR API. NVR validates the voice, rate-limits the request, uses a fixed sample phrase, and returns generated MP3 audio. Repeated samples are cached server-side to reduce unnecessary Azure usage.

Understanding the catalog
What customers should know about Azure natural voices.
Locales matter
A voice labeled en-US, en-GB, en-PH, or another locale is designed around a particular language and regional speaking profile.
Pronunciation can vary
Names, acronyms, abbreviations, medical terms, product names, URLs, numbers, and unusual punctuation may sound different from what a particular listener expects.
No voice is guaranteed forever
Microsoft or NVR can add, update, replace, region-limit, or retire voices. Business workflows should have an acceptable backup voice.
Preview uses controlled text
The public website intentionally does not provide an unrestricted free-text Azure synthesizer. This protects NVR from abuse and uncontrolled cloud charges.
Cloud narration uses plan allowance
Inside the Reader, supported natural narration can count toward the applicable monthly narration allowance regardless of which production voice is selected.
Customers need no Azure account
NVR owns and controls the backend connection to its Speech resource. Customers do not receive NVR Azure subscription keys or private service credentials.
WAV rights follow source rights
Exporting synthetic narration does not give a customer copyright or other rights in source content the customer was not already entitled to use.
Review important output
When pronunciation or exact wording matters professionally, preview representative text in the Reader and review generated audio before distribution.
Natural Voice Reader
