02 · Overview
Balabolka and Murmur side by side
Every Balabolka entry below comes from Balabolka's official website. Where the site did not say, the table says so instead of guessing.
| Balabolka | Murmur | |
|---|---|---|
| Pricing model | Free | One-time purchase |
| Free tier | Balabolka is free of charge for non-commercial use. | No free trial; 7-day refund |
| Paid plans | Commercial license: €80 (one-time) | $49 one-time for one Mac, no free trial, 7-day refund |
| Usage limits | No per-request character cap is set by Balabolka itself; the text size for conversion is limited by the temporary WAV audio format (just under 4 GB), so the site recommends splitting a big document and converting each part separately. (It can also work around the ~100-symbol limit of Google Translate TTS by splitting and merging parts.) | No character, minute or credit limits |
| Platforms | Windows | macOS 15 or later on Apple Silicon |
| Where speech is generated | Locally on your device | Local, on your Mac |
| Works offline | Yes | Yes, after models are downloaded |
| Voice cloning | No | Yes, from a short reference recording |
| Languages | No single headline language count; the app itself contains no voices and coverage depends on installed engines. The site lists Microsoft Speech Platform support for 26 languages for speech synthesis and provides downloadable Microsoft natural voices across many languages and locales (e.g. English, Spanish, French, German, Chinese, Japanese, Korean, Arabic, Hindi, Portuguese and more). | 600+ with the optional OmniVoice model |
| Export formats | WAV, MP3, MP4, M4A | WAV, M4A |
| Commercial use | Balabolka is free of charge for non-commercial use. But if you intend to use the application, for example, to create and distribute audio files on paid platforms, you need to purchase a license. Also, if Balabolka is used on a computer within a commercial organization, a license must be purchased. The license is €80. Balabolka does not contain any voices (speech engines) inside it; it is up to the user to resolve licensing issues for commercial use of voices. | Depends on the license of the model you generate with; check each model's license |
