Windows text to speech can mean three different workflows: using voices installed on a PC for Narrator or an app, generating audio and subtitle cues from text with edge-tts, or dubbing dialogue to fit an existing video. The key difference is what the speech is for—and what its timing follows. Windows voices serve accessibility and apps; edge-tts follows the text it synthesizes; a video dub has to fit the source video’s timeline.
Which Windows text-to-speech option fits your job?
| Option | Where speech is generated | Best suited to | Timing follows |
|---|---|---|---|
| Built-in Windows voices | Installed speech engine on the PC | Narrator and Windows apps | The app or accessibility experience |
edge-tts |
Microsoft’s online consumer Read Aloud endpoint, accessed by a community Python package | Generating audio files from supplied text, with optional SRT cues | The generated speech |
| Azure AI Speech | A separately configured Microsoft cloud service | Applications needing a documented API and service integration | The synthesis request and any application logic |
| Video dubbing | A production workflow using a TTS engine or recorded speech | Replacing or translating dialogue in an existing video | The source video’s timeline and audiovisual content |
These options are not interchangeable. If you want Windows to read screen content, start with Narrator. If you want a file from a text script, a TTS generator such as edge-tts may fit. If that file must replace dialogue in a video, you also need to adapt and synchronize it. For a supported developer integration, evaluate Azure AI Speech separately.
What built-in Windows voices are available?
There is no single voice inventory that applies to every Windows PC. Available voices depend on the language resources installed on that machine, and Microsoft’s documentation lists supported voices by language, country, or region for Windows 10 and Windows 11. A voice appearing in Microsoft’s list does not mean it is already installed on your computer. See Microsoft’s supported languages and voices appendix for the documented list and guidance.

Add or change a voice for Narrator
Narrator is Windows’ screen reader and accessibility feature, rather than a general-purpose audio-export tool. Microsoft documents adding a language voice through Narrator settings and the Speech settings page; the exact available choices depend on the installed language resources. Its Narrator customization guide describes voice and other Narrator settings.

Use installed voices in a Windows app
A Windows application can use the Windows.Media.SpeechSynthesis API to enumerate installed voices and select one for synthesis. Microsoft says, “Only Microsoft-signed voices installed on the system can be used to generate speech.” That means a developer should query the current PC’s available voices rather than assume a fixed list. The SpeechSynthesizer API documentation covers enumeration and selection.
This local Windows API is distinct from Microsoft’s hosted Azure AI Speech service. An installed voice can be useful for system accessibility or app speech without being an Azure voice or granting access to an Azure API.
What is edge-tts, and can it save an MP3 and SRT?
edge-tts is a Python package with a command-line tool that sends text to Microsoft’s online Edge Read Aloud speech service. The project says it does not require Microsoft Edge, Windows, or an API key, and its README shows workflows for writing audio and subtitle files. Those conveniences do not make it an official Microsoft developer API or establish a service guarantee or commercial-use permission. Its operation depends on a consumer online endpoint that may change independently. See the edge-tts project README for its installation and usage examples.

The tool can produce SRT cues from speech-boundary metadata. Those cues correspond to the text that edge-tts synthesized; they are not automatically aligned to an existing video’s dialogue, and the tool does not turn an SRT file into a finished video dub. The project’s SubMaker implementation handles subtitle generation from boundary events.
Example command-line workflow
Install Python and the package as described in the project README, then use its CLI help to confirm the flags available in your installed version. A typical invocation is:
edge-tts --text "Hello from Windows." --write-media speech.mp3 --write-subtitles speech.srtThe expected outputs are an audio file and an SRT file for the generated speech. Check the README for current command syntax; package behavior and compatibility can change as the online endpoint changes.

Why generated SRT text may need checking
The project handles word- or sentence-boundary metadata, and its implementation splits input when it reaches a byte-length limit. Text normalization can also affect what is spoken: for example, abbreviations may be expanded or numbers spoken as words. The project’s Communicate implementation and maintainer discussion of SubMaker describe these details. Review generated captions against the audio rather than assuming the SRT will reproduce the input text exactly.

Why an SRT file does not automatically make a video dub fit
“Never fits” is too absolute: subtitles can be useful source material for dubbing. The problem is that subtitle cues are not a complete dubbing plan. They may be translated, shortened for reading, or timed to appear on screen rather than to match a natural spoken delivery. edge-tts’s SRT cues, by contrast, are derived from the speech it generated. The two timing systems have different anchors.

A dub must work against the existing video’s timeline and content. A translated line can take longer or less time to say than the original; a cue’s start and end times do not by themselves determine delivery, pauses, speaker turns, or where a replacement line should begin and end. This is a workflow consequence of the difference between generated-speech boundaries and an existing video’s timing—not a claim that subtitles can never help.
A practical subtitle-to-dub workflow
- Use the SRT as a script source, not as finished timing. Check the subtitle text against the dialogue and intended meaning. For translated dialogue, have a fluent speaker review the wording.
- Synthesize and listen to the lines. Check pronunciation, wording, pauses, and whether the delivery sounds suitable for the scene.
- Compare each spoken line with the video timeline. Identify lines that start too early or late, overrun the available window, or clash with speaker turns and visible action.
- Adjust the fit. Depending on the line, revise wording, pauses, speech rate, cue timing, or the audio edit. Changing rate alone is not a reliable universal fix.
- Review the assembled dub against picture. An editor should check synchronization and transitions in the final video, not just the generated SRT.
When should a developer use Azure AI Speech instead?
Azure AI Speech is a distinct, documented Microsoft service with authentication, regional endpoints, text-to-speech support, and an API for retrieving supported voices. Voice and locale availability depend on current service support and region. Microsoft’s Text to speech API reference (REST) describes the REST options and says, “Use it only in cases where you can’t use the Speech SDK.” Microsoft recommends the Speech SDK when an application needs event subscriptions or richer processing insight.

Quick Recap
Which option should you choose?
- For screen reading: use Narrator and add the language voice you need through Windows’ speech settings.
- For speech inside a Windows app: enumerate installed voices with
Windows.Media.SpeechSynthesisand handle the voices actually present on each system. - For quick text-to-audio files: consider edge-tts if its online endpoint, project status, and terms suit your use.
- For a documented cloud integration: assess Azure AI Speech, including its regional availability, authentication, and SDK capabilities.
- For replacing video dialogue: treat subtitles as one input; adapt the speech and synchronize it against the video.
