Write or import your script, choose a voice and select Generate speech. Listen to your take, refine the delivery and download the version you like.
How much text fits in a take?
You can use up to 5,000 characters in one script, including all dialogue turns. Split longer documents into sections, then download your takes together.
Can I create a conversation?
Yes. Open Multi-speaker, choose a voice for each turn and set the gap between lines. Your dialogue is combined into one audio file.
Where are my scripts and recordings stored?
Your script is sent to Microsoft’s online speech service for synthesis. The server caches audio for 48 hours, then removes expired files during its next cleanup. Finished takes are also saved in this browser. Clearing browser data removes these local copies. Members can save selected recordings to cloud and save projects to their account; those copies stay until deleted from the member workspace or the account is deleted.
Why might a voice be temporarily unavailable?
Voice availability depends on the upstream speech service. If a request fails, wait a little and try again. AI Text to Speech does not promise unlimited use or uninterrupted availability.
DOCUMENTS, CHAPTERS & LONGER IDEAS
Give a document a listening edition.
Bring a PDF or Word document, check its reading order and divide longer writing into natural sections. Keep each part within the studio limit and download a complete collection when you finish.

About the voice catalog
Explore the available voices and choose the delivery that suits your project. A regional label helps identify a voice’s language and locale; it does not promise a specific personal accent. Voices labeled Multi support multilingual reading. Preview a short sample and check your own names and terminology before generating a longer recording. Avatars are AI-generated fictional characters, not photographs of voice performers.
This website is independent of Microsoft. The catalog can change, and request limits and source availability apply.

A FEW POINTERS FOR A GREAT RECORDING
Write it. Make it sound like you.
Write for a listener
Keep each sentence focused on one idea. Read the script out loud once before generating it. Spell out unusual abbreviations and write numbers the way you want them spoken.
Use [[p700]] for a 0.7-second pause. Each pause can be up to 10 seconds, with 60 seconds of pauses in total and a maximum of 50 pause markers.
Build a conversation
Choose Multi-speaker and give each turn a speaker name and voice. Add lines in the order they should be heard. Set a short gap between turns for a natural back-and-forth.
Every turn counts toward the same script character limit.
From document to download
Upload a PDF with selectable text or a DOCX file up to 15 MB. Image-only PDFs need OCR first. Long documents should be divided into shorter sections.
MP3 is easy to share. WAV works well for editing. Add your own MP3 or WAV soundtrack from a finished take; the music is mixed at 15% volume.
Your data and the voice service
Scripts are processed by Microsoft’s online speech service to create your recording. The server caches audio for 48 hours and clears the job’s script when processing ends. Cleanup runs every five minutes.
Takes are saved locally in your browser. Download the recordings you want to keep. Your saved takes remain in this browser until you remove them or clear site storage.
AI TEXT TO SPEECH / MEMBER WORKSPACE
Your creative workspace.
A home for your scripts, signature voices and finished takes.
Choose a listening copy or an editing file without overcomplicating your export.
Two useful output choices
MP3 compresses audio and is convenient for sharing, drafts and everyday listening. WAV is an uncompressed output in this studio and is useful when a downstream editing workflow expects it. Your destination determines which one to choose.
Conversion has a limit
Converting an existing MP3 into WAV makes an uncompressed representation of the decoded audio. It does not recreate information already removed by MP3 compression or make a synthetic voice more expressive.
Keep the delivery consistent
Before exporting multiple takes, compare their speaking pace and volume. A set of consistent files often matters more than a change of container. Keep clear filenames so you can put the files in the intended order.
Check the receiving tool
A video editor, telephone system and website may expect different sample rates or codecs. Test a short file with the tool you plan to use before producing a large collection. Keep the original takes so you can make another export when needed.
Make a small test first
Choose a voice, generate a short take and listen before building a longer project. Scripts are processed by an online speech service; avoid material you should not share with an outside provider.
