# Suno v5.5 lets users sing with their own cloned voice and fine-tune personal models

Suno released v5.5, its last pre-licensing flagship, with three personalization features: Voices (verified cloning of the user's own singing voice), Custom Models (fine-tuning a private v5.5 on at least 6 of the user's own tracks) and My Taste (learned style preferences). It moved consumer AI music from "generic song" toward "your voice, your sound".

## Key facts
- Announced 2026-03-26 on Suno's blog (MBW dated the release Friday 2026-03-27)
- Voices: record/upload your own singing; a verification step has the user speak a random phrase to prove it is their voice; voices private by default; Pro/Premier only
- Custom Models: upload at least 6 tracks from your own catalog to tune v5.5 to your style; up to 3 custom models per user; Pro/Premier only
- My Taste: learns preferred genres, moods and references and applies them via the Magic Wand; all users
- v5.5 was retired on 2026-09-09 when Suno replaced its lineup with the licensed-data v6 family; Voices and Custom Models carried over

## What happened

Suno shipped v5.5, billed as its "most expressive" and "most personal" model, with richer arrangements and sharper vocals than v5. The headline was personalization: paying users could capture their own singing voice (with an anti-impersonation verification step) and have Suno sing generated songs in it, and could fine-tune a private copy of v5.5 on their own catalog. Suno framed it as "The best music starts with a human."

## Why it matters

It brought consumer-grade voice cloning and per-user fine-tuning into the most popular AI music app, raising both creative possibilities and impersonation/consent questions, six months before Suno retired all of its unlicensed-data models in favor of v6.
