AI Audio Generation Leaderboard
Top AI audio models ranked across text-to-music, text-to-song and text-to-speech — pairwise-matched on real prompt groups, scored by free audio ensembles (MuQ-Eval, CLAP, UTMOS, Whisper, Audiobox) and ordered by mean per-group Elo.
How this leaderboard is measured
Each track pits every model against its rivals on the same prompt groups. Speech clips are scored by a UTMOS-naturalness + Whisper transcription-accuracy + Audiobox ensemble; music and song clips by MuQ-Eval quality with CLAP prompt-adherence. Ensemble wins become per-group Elo with a Bradley–Terry cross-check, so a rating reflects consistent preference across prompt groups rather than one lucky clip.
- What it is: a controlled listening benchmark for generative audio — the same prompt groups and the same scorer ensembles every run, so a move on the board means the models changed, not the test.
- Who runs it: Pixazo's research team writes the prompt groups, generates every clip, and reviews the results. Scoring is delegated to free, reproducible audio ensembles — UTMOS, Whisper and Audiobox for speech; MuQ-Eval and CLAP for music and song — under one fixed rubric, so no single listener's ear (or fatigue) can tilt a rank.
- Tracks: three are live — text-to-music, text-to-song and text-to-speech; switch between them with the toggle under the hero.
AI & methodology disclosure: the audio benchmark is designed, run and reviewed by Pixazo's research team; clips are scored by the free audio ensembles described above, not by crowd voting. Pixazo hosts these models but does not own them — each provider is named beside its model, and Pixazo's own Tracks model competes under the identical rubric.

Frequently asked questions
Which AI music generation model is best in 2026?
Google's Lyria 3 leads Pixazo's text-to-music board at 1,036 mean Elo, with Lyria 2 close behind — Google currently holds the top three music slots. Stability AI's Stable Audio and ElevenLabs Music complete the track.
Which text-to-speech model tops the speech track?
ElevenLabs v3 leads the speech board at 1,078 mean Elo with the strongest naturalness scores. Alibaba's Qwen3-TTS is the value story — second place at a fraction of the per-clip price — followed by Microsoft's VibeVoice pair, Resemble AI's Chatterbox and Gemini Flash TTS.
How do the music, song and speech tracks differ?
Text-to-music generates instrumental audio from a written prompt; text-to-song adds vocals and lyrics on top of the composition; text-to-speech turns text into spoken narration. Each has its own board scored by an ensemble tuned to that job — switch tracks with the toggle under the hero.
How are the audio clips scored?
Speech clips run through a UTMOS-naturalness + Whisper transcription-accuracy + Audiobox ensemble; music and song clips through MuQ-Eval quality with CLAP prompt-adherence. Ensemble wins become per-group Elo with a Bradley–Terry cross-check, and every model faces the same prompts under the same rubric.
Is Pixazo's own Tracks model given any advantage?
No — if it were, it would not be losing. Tracks trails ACE-Step XL on the text-to-song board and holds second place; every clip it generates goes through the identical MuQ-Eval + CLAP scoring pipeline as its competitors.
What does the per-clip cost on this board mean?
It is the public per-generation price on Pixazo's gateway for a typical clip — roughly 45 seconds of music or song, or 15 seconds of speech. The value view divides mean Elo by that price to surface which models deliver the most quality per dollar.
