Use tool ↗About FlowSpeech
FlowSpeech turns written text into narration with more hand control than most browser TTS tools: inline bracket tags set emotion, accent and delivery such as whisper or shout, and timed pauses are written into the script rather than left to the model. It detects the speakers in a multi-character script and assigns each a different voice, and it takes PDF, Word, PowerPoint, EPUB, RTF and image files as input rather than paste only. The catalogue is 30 voices in four styles, with standard voices covering 100+ languages. Signed-in free use gives 10,000 credits a month; paid plans start at $19 for 200,000 credits and, according to the pricing page, include API access against the same credits. The footer names FlowSpeech with no legal entity or country.

Pros & cons of FlowSpeech
The tagging system is the reason to choose it: emotion, accent and pause markers give you control that one-click TTS tools hide, and speaker detection makes dialogue and audiobook scripts far less tedious. Prices moved up this autumn — Basic is $19 rather than $15 — and the pricing page now promises API access on paid plans, though no API documentation was found. The 30-voice catalogue is small and the vendor is anonymous.
Pros
- Inline tags for emotion, accent and delivery, plus timed pauses
- Automatic speaker detection with a distinct voice per speaker
- Accepts PDF, Word, PowerPoint, EPUB and image files, not paste only
- Free tier of 10,000 credits a month when signed in
- Standard voices cover 100+ languages
Cons
- Only 30 voices, which is small next to the big TTS catalogues
- No company name, country or ownership published
- Per-request cap of 100,000 characters forces long books to be split
- API access is advertised on the pricing page but no documentation page was found
Best for
- audiobook and dialogue narration with several characters
- narration that needs deliberate pacing and emphasis
- converting existing PDF, Word or EPUB files to audio
Not for
- cloning a specific person's voice
- anyone who needs a documented, supported API today
Watch out: The pricing page lists 'TTS API access' on paid plans, yet the API path on the site returns 404; confirm the API exists before paying for it.
