As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].
add_favorite_voiceAdd favorite voiceSave a voice to the user's favorites (only when the user asks).
create_upload_urlUpload a video/audio fileGet a one-time URL to upload a local video or audio file (mp4, mov, webm, mkv, mp3, wav, m4a...) up to 2 GB. Upload with HTTP PUT of the raw bytes, e.g. `curl -T video.mp4 "<upload_url>"` (valid 15 minutes), then pass `public_url` to transcribe_media or localize_video. Only files uploaded here (or on ttsforfree.com) are accepted; YouTube and other external links are never downloaded. If you cannot run commands, ask the user to upload the file on https://ttsforfree.com/en/video-localization/ and paste the file link.
design_custom_voiceDesign a custom voiceCreate a new personal AI voice from a natural-language description (Gemini Voice Design). Uses one slot of the user's custom-voice quota - confirm with the user first. Good for a unique narrator or a character voice in a video/podcast. Returns the new `voice` token.
estimate_video_localizationEstimate video dubbing costread-onlyEstimate the credits to dub one video into one or more languages (speech-to-text + translation + voice + video merge) before running localize_video. Pass video_url (duration is measured) or duration_seconds.
get_account_statusAccount statusread-onlyShow the user's plan tier, remaining characters/credits, max characters per request, max blocks per multi-voice/SRT job and API rate limits. Call before large jobs.
get_job_detailJob segments (for Remotion / editors)read-onlyGet a multi_voice_to_speech or srt_to_speech job with every segment: text, voice and its own audio_url, plus the merged audio. Use it to build captions or a Remotion/NLE timeline (one <Sequence> per segment; measure each file's duration in the renderer).
get_job_statusJob statusread-onlyCheck a speech job created earlier. Returns status (PENDING | SUCCESS | ERROR) and audio_url once SUCCESS. Never guess or fetch an audio URL before SUCCESS.
get_localization_statusVideo dubbing statusread-onlyStatus of localize_video jobs: current step, and when Completed the dubbed audio_url, final_video_url and translated SRT for each language.
get_transcriptionTranscription statusread-onlyCheck a transcribe_media job and get its SRT once finished.
get_voice_detailsVoice detailsread-onlyGet full metadata for one voice token: persona, use case, accent, pitch, styles, preview audio and credit cost.
list_favorite_voicesMy favorite voicesread-onlyList the voices the user marked as favorites, in their saved order. Check this first when the user did not name a voice.
list_languagesList languagesread-onlyList every language supported by TTSForFree text-to-speech. Returns language codes to pass to list_voices.
list_my_custom_voicesMy custom voicesread-onlyList the user's personal voices created with Voice Design (from a text prompt) or Voice Clone (from an audio sample), plus the remaining custom-voice quota. Use `voice` from the result in any speech tool.
list_recent_jobsRecent jobsread-onlyList the user's most recent speech jobs with status and audio URLs, to reuse earlier audio instead of paying again.
list_voicesFind voicesread-onlySearch the AI voice catalog for one language. Each result has a `voice` token (v1:...) - pass it unchanged as `voice` to text_to_speech, multi_voice_to_speech or srt_to_speech. Results are sorted by popularity; `can_use=false` means the user's plan cannot use that voice. Prefer the user's favorite or custom voices when they exist.
Show 6 more tools
localize_videoDub a video into other languagesFull automatic dubbing of an uploaded video: transcribe once, translate, voice every target language with its own voice and render a dubbed video per language. Each language returns an audio_url (voice track aligned to the original timeline - upload it to YouTube Studio as a multi-language audio track) and a final_video_url. Takes several minutes: returns job_guids immediately; poll get_localization_status. Confirm the cost with estimate_video_localization for long videos.
multi_voice_to_speechMulti-voice audio (podcast / dialogue)Render ordered segments, each with its own voice, into ONE merged MP3. Use for podcasts, dialogues, interviews, audio dramas or explainer videos with several speakers when there are no fixed timestamps. Consumes credits.
remove_favorite_voiceRemove favorite voicecan change or delete dataRemove a voice from the user's favorites (only when the user asks).
srt_to_speechSubtitles to speech (video voiceover / dubbing)Create ONE MP3 that follows a subtitle timeline: every cue starts at its timestamp and speech speed auto-fits the cue duration. Use for video voiceover, dubbing translated subtitles, YouTube localization, tutorials and any edit where audio must line up with existing video. Pass either raw `srt` (SRT or WebVTT text) or `segments` with start_ms/end_ms. For several speakers set `speaker_voices` and prefix cue text with '[Name]' or 'Name:'. The resulting MP3 starts at 00:00 of the video, so it can be muxed directly with ffmpeg (commands are returned). Consumes credits.
text_to_speechText to speechConvert one text into one MP3 with one voice. Use for narration, voiceover scripts, articles, lessons, announcements or any audio whose length can follow the speech. Consumes credits (characters x voice rate). Returns job_id, status and audio_url when ready.
transcribe_mediaTranscribe video/audio to SRTSpeech-to-text for an uploaded video or audio file: returns timestamped SRT (the timeline to rewrite, translate or re-voice with srt_to_speech). Credits are charged per second of media, measured by the server. Use language = the spoken language code from list_languages.
