F5-TTS Voice Cloning

F5-TTS is a reference-audio text-to-speech model: upload a short clip of someone speaking, type new words, and get back speech that follows your script in a similar voice — without training a custom model.

F5-TTS is open source with official docs and public weights on Hugging Face — On Vocalove you never call the API yourself. Pick Clone voice in the tool above.

What is F5-TTS?

F5-TTS (Flow Matching-based Fast and Faithful Text-to-Speech) is an open-source family of TTS models built for zero-shot voice cloning. Instead of picking a fixed narrator voice, you supply a reference recording — often just a few seconds — and the model learns timbre, pace, and tone from that clip, then synthesizes brand-new speech for whatever text you write.

Traditional voice cloning meant collecting hours of studio audio and fine-tuning a model per speaker. F5-TTS skips that: one clean sample is enough to stand in for a full custom voice. That makes it practical for tribute messages, personal keepsakes, localized narration, and any project where the voice must feel like someone specific.

On Vocalove, clone mode runs F5-TTS in the cloud — you upload a reference clip, type your script, and download WAV audio in the browser. No local GPU or developer setup required.

  • Zero-shot cloning

    No dataset prep, no per-voice fine-tune — one reference clip defines the output timbre.

  • Reference-driven

    The model reads voice character from your sample audio, not from a preset voice library.

  • English & Chinese

    Synthesize in either language from the same reference clip — useful for bilingual keepsakes.

  • Browser-ready

    Record or upload a sample, type your script, and generate cloned speech without leaving Vocalove.

How F5-TTS works (the model)

At a high level, F5-TTS is reference-audio-driven synthesis: your clip teaches the model what the voice sounds like; your text tells it what to say.

  1. Step 1

    Reference audio in

    You provide a short WAV, MP3, M4A, or similar clip of one speaker. Vocalove strips long silences before synthesis so the model focuses on actual speech.

  2. Step 2

    Voice characteristics extracted

    F5-TTS uses a diffusion-style architecture to learn timbre and speaking style from that single sample — pitch contour, rhythm, and vocal color — without a separate training step for each person.

  3. Step 3

    New text synthesized

    You pass the words to speak as your script. The model generates fresh audio that follows your script while staying close to the reference voice. Output is typically a WAV file you can download or pipe into a talking-photo video step.

What F5-TTS is good for

Situations where a generic narrator is not enough — you need speech that sounds like a real person.

  • Memorial & tribute messages

    Turn a voicemail or home recording into new words of comfort, thanks, or remembrance — in a voice family and friends recognize.

  • Talking photo videos

    Generate the audio track first with F5-TTS, then animate a portrait on Talking Photo Videos so the face lip-syncs to the cloned speech.

  • Personalized greetings

    Birthday lines, reunion surprises, or holiday messages that carry someone’s actual vocal character instead of a stock AI voice.

  • Draft before you record

    Hear how a script lands in a similar timbre before committing to a full studio session — useful for pacing and wording.

F5-TTS vs built-in preset voices

Both live in the same Vocalove tool — they solve different problems.

F5-TTS on Vocalove

When you select Clone voice in the tool above and click generate, Vocalove runs F5-TTS on your sample and script, then returns synthesized WAV/MP3 for preview and download.

Try F5-TTS in three steps

Upload a sample, type your script, and generate cloned speech in the browser.

  1. Step 1

    Record or upload a sample

    Three to thirty seconds of clear speech in a quiet room. mp3, wav, or m4a uploads work; you can also record directly in the browser.

  2. Step 2

    Type your script

    Write what you want heard. F5-TTS supports English and Chinese text; keep lines natural for best results.

  3. Step 3

    Generate cloned speech

    Vocalove runs F5-TTS and returns audio — usually within one to three minutes. Add a portrait later if you want a talking photo video.

Why choose F5-TTS?

Generic TTS sounds like a narrator. F5-TTS is built for zero-shot cloning: a few seconds of real speech can stand in for a full voice model fine-tune. That fits tribute messages, birthday lines, and keepsakes where cadence and warmth matter.

Vocalove wraps F5-TTS in a browser workflow — no Python notebook, no local GPU. Clone mode costs roughly twice the built-in TTS rate in credits; see pricing for packs.

  • Clone mode billing: about 9 credits per 1,000 characters (vs built-in preset TTS).
  • Best samples: single speaker, minimal background noise, natural talking pace.
  • Optional next step: pair cloned audio with a portrait on Talking Photo Videos.

What to do after F5-TTS audio

Happy with the clone? Download the MP3. Ready for lip-sync? Open Talking Photo Videos, upload the same portrait and use clone mode again — or start from the homepage and add a photo when you are ready.

F5-TTS FAQ

What does F5-TTS stand for?
F5-TTS refers to a Flow Matching-based Fast and Faithful Text-to-Speech model family. In practice it means zero-shot voice cloning: one reference audio clip plus new text, without per-speaker training.
What is zero-shot voice cloning?
Zero-shot means the model clones a voice from a single sample at inference time — no fine-tuning on hours of that person’s speech. F5-TTS reads timbre and style from your reference clip and applies it to whatever script you provide.
Which model powers clone mode?
F5-TTS. Vocalove sends your reference audio and script; the model returns synthesized WAV audio. Long silences in your sample are trimmed before synthesis for better results.
How long should my F5-TTS reference sample be?
Three to thirty seconds is the sweet spot. Clear, single-speaker speech beats a long noisy clip. If cloning fails, try a shorter, cleaner sample or switch to a built-in voice to test your script first.
When should I use built-in voices instead of F5-TTS?
Built-in presets are faster and cheaper for drafts, directions, or when you have no sample yet. Use F5-TTS clone mode when the output must sound like a specific person you have permission to imitate.
Does F5-TTS make the talking photo video?
No — F5-TTS outputs audio only. Talking photo videos add a portrait step so the face lip-syncs to your cloned speech. Clone mode uses F5-TTS first, then optionally animates the face to match.
