The tool offers 12 distinct voice characters spanning soft female, powerful male, duet, and choir options. It supports vocal generation in 11 languages with 13 vocal technique settings including belting, falsetto, and whisper.

Create AI Vocals in 3 Simple Steps
Describe Your Vocal Vision
Type a plain text description of the vocal style, mood, and genre you want. Select a voice character, emotion, and language from Musely's guided interface. No MIDI or music theory knowledge required.
Add Lyrics or Let AI Write Them
In Advanced settings, blend Music Styles tags — such as vocaloid-style, ethereal, future bass, a cappella, or cinematic — to define production texture. Set Vocal Technique from 13 options including Belting, Falsetto, Whisper, Vibrato-heavy, Smooth Legato, and Vocal Runs. Then choose Harmony & Layers from 7 arrangements: Solo Voice Only, Light Harmonies, Rich Harmonies, Doubled Lead, Call and Response, Layered Choir Background, or Unison Ensemble. Stacking these controls gives Musely precise synthesis direction.
Generate and Download Your Track
Hit generate and Musely's AI processes your request in approximately 60 seconds. Preview the synthesized vocal track, make adjustments if needed, and download the final audio.
Who Uses Musely Vocal Synthesizer
Add Professional Vocals to Home Recordings
I used to spend $200 per session hiring session singers. Musely's vocal synthesizer gives me 12 different voice characters I can try instantly. I produced 3 complete demo tracks in one weekend without leaving my apartment.
Create Original Character Vocal Tracks
I love creating vocal tracks but VOCALOID's MIDI interface always frustrated me. Musely lets me type what I want in plain English and get results in about a minute. I've made 14 original tracks for my channel this month.
Prototype Song Ideas Before Studio Sessions
Before going to the studio, I test melodies and lyrics on Musely. The AI vocal synthesis helps me hear how different vocal styles fit my songs. It cut my pre-production time by about 65% compared to recording scratch vocals myself.
Generate Original Music for Video Content
Licensing vocals for my videos was expensive and time-consuming. With Musely's vocal synthesizer I create custom vocal tracks in 11 languages for my international audience. My production costs dropped roughly 40% since switching.
Produce Character Theme Songs and Cutscene Vocals
Each character in my RPG has a unique vocal theme now. Musely's 12 voice characters and emotional controls let me match synthesized vocals to each character's personality. I created 8 character themes in 2 days instead of the weeks it would have taken with contractors.
Demonstrate Vocal Techniques and Styles to Students
I use Musely's vocal synthesizer in my classes to demonstrate 13 different vocal techniques from belting to falsetto. Students hear the differences instantly instead of me describing them. Engagement in my music theory classes improved by about 30% this semester.

What Musicians Say About Musely
4.7/5 from 9,843 reviews
“Musely's vocal synthesizer replaced my entire demo recording workflow. I used to spend 4 hours recording scratch vocals for each song. Now I type a description and get a polished vocal track in 60 seconds. I've completed 22 demos this quarter compared to 8 last quarter.”
“As someone who makes Vocaloid content, switching to Musely saved me roughly 15 hours per week on MIDI programming. The text-based input is so much faster. My output went from 2 tracks per month to about 8, and the vocal quality honestly rivals dedicated synth software.”
“I teach vocal production at a community college and Musely became my go-to demonstration tool. Students can hear 13 different vocal techniques side by side without hiring multiple singers. Course feedback scores improved from 3.8 to 4.5 out of 5 after I started using it in lectures.”
