FlowSpeech is a browser-based AI voice and audio-production platform designed for content creators, educators, marketers, podcasters, audiobook producers, video teams, and other users who need professional narration without recording every line manually. Its central text-to-speech studio analyzes the context, emotion, rhythm, and meaning of a script before generating the audio, helping the output sound more expressive than a basic text reader.
Users can choose between Single Speaker, Multi Speaker, and Instant generation modes. Single Speaker is intended for narration and monologues, while Multi Speaker automatically detects different characters in a script, separates their dialogue, and assigns suitable AI voices. FlowSpeech currently promotes more than 30 voices across styles such as news, marketing, storytelling, and character performance, with support for over 70 languages.
Creators can directly control delivery by inserting instructions into the script. Emotion and accent tags can request performances such as whispering, shouting, or speaking with a particular accent, while pause commands provide precise control over timing. The platform can also automatically analyze uploaded scripts and insert appropriate emotional instructions. It accepts pasted text and files including PDF, DOC, DOCX, PPT, PPTX, TXT, RTF, EPUB, and images, with paid plans supporting up to 200,000 characters in one request.
Beyond text-to-speech, FlowSpeech offers AI dubbing that aims to preserve the original speaker’s identity while translating speech and synchronizing it with visible lip movement. It also includes a voice changer that preserves the source recording’s emotion, accent, and pacing, an AI sound-effects generator with duration controls, and an audio-to-video tool that animates a portrait using an uploaded voice track.
A permanent Free plan provides 10,000 monthly credits for signed-in users, while Basic, Pro, and Scale subscriptions increase monthly allowances and maximum generation capacity.
