Compose a melody, choose an Ah, Eh, Ee, Oh, or Oo vowel, then shape the vocal register, breath, vibrato, envelope, and stereo width before exporting a WAV.
Start with a voice preset, then refine the vowel and vocal behavior.
Enter notes separated by spaces. Use a dash for a rest; up to 32 steps are supported.
The synthesizer combines pitched harmonics with vowel formants, breath noise, vibrato, and an amplitude envelope to produce a controllable synthetic voice.
Choose Ah, Eh, Ee, Oh, or Oo and switch the resonant formants that define the vocal character.
Use Soprano, Alto, Tenor, or Bass to shift the formant profile and start the note pad in a practical octave.
Adjust brightness, breath, vibrato depth and rate, attack, release, stereo width, tempo, and legato.
Render up to 32 melody steps locally, preview the generated phrase, then download a normalized stereo WAV, MP3, M4A, FLAC, or OGG file.
Start with a preset or build a vocal patch from the individual controls.
Select Solo Ah, Airy Choir, Bright Ee, or Robot Oo as a starting point.
Choose the register and vowel, then adjust brightness, breath, vibrato, envelope, and stereo width.
Type notes such as C4, F#4, or Bb3, use a dash for a rest, or add notes from the chromatic note pad.
Set the tempo and legato, render the complete phrase, preview it, then choose WAV, MP3, M4A, FLAC, or OGG for download.
A vowel synthesizer is useful when you need a pitched human-like texture without recording lyrics.
Create airy sustained phrases that can sit behind instruments, pads, or a lead vocal.
Build short synthetic vocal motifs for pop, dance, ambient, game, and experimental tracks.
Enter a note sequence to audition a vocal-style melodic idea before arranging or recording it.
Use tight envelopes and unusual formants for robotic prompts, tonal alerts, and character sounds.
Small changes to articulation and formants usually sound more natural than maximizing every control.
Use higher notes for Soprano and Alto and lower notes for Tenor and Bass to keep the vocal color convincing.
A little breath adds air and softness, while a high setting creates a deliberately whispered texture.
Increase both for connected choir phrases, or reduce them for rhythmic robotic articulation.
No. It is a browser-based formant synthesizer that creates pitched vowel sounds. It does not imitate a real singer or generate sung lyrics.
Use note names from C1 through C8, including sharps and flats such as F#4 or Bb3. Separate notes with spaces and use a dash for a rest.
One render can contain up to 32 steps. Duration depends on the selected tempo, release, and number of rests.
No. The oscillator, formant, noise, vibrato, envelope, stereo rendering, preview, and WAV, MP3, M4A, FLAC, or OGG export run locally in the browser.
Download the finished synthetic vocal phrase as WAV, MP3, M4A, FLAC, or OGG. WAV and FLAC are useful for higher-fidelity production work, while MP3, M4A, and OGG are more compact for sharing and playback.
Shape vocal formants, register, breath, vibrato, envelope, stereo width, and melody, then export WAV, MP3, M4A, FLAC, or OGG.
Detect vocal pitch, snap notes to a musical scale, preview the correction, and export a mainstream audio format.
Use chipmunk, robot, demon, anime, deep voice, alien, radio, and advanced controls.
Choose from 28 American and British voices, adjust speed, preview, and export MP3 or WAV.
Upload or record speech, generate timestamped text, edit the transcript, and download TXT or SRT.
