Suno Speech vs ElevenLabs Eleven v4: One-Pass Soundtrack vs Expression Control

Suno Speech is a public-beta feature Suno opened on Oct 1, announced by chief product officer Jack Brody in the company's blog. Users enter a one-line idea, a poem or a script, then describe the voice and soundtrack style they want; the model generates the narration and an original background score in one pass as a single track, with a toggle to switch the music off and keep speech alone. It lives in Suno's Create tab on web, iOS and Android, with two modes — Simple (a short description) and Advanced (a full script, with controls for voice gender, speaking style and take-to-take variety) — and clips run to about eight minutes.

ElevenLabs Eleven v4 is the new-generation speech model ElevenLabs released on Sep 28, alongside a low-latency variant, v4 Turbo. The company says the new architecture follows a script's tone, pacing and context more closely and keeps speaker identity steadier over long passages; the in-sentence expression tags (audio tags) introduced with v3 are expanded into stackable tags that the model follows in sequence, covering laughter, whispers, pauses and sound effects. Language coverage grows from 70+ to 90+ languages; the company says the largest quality gains are in Japanese, Brazilian Portuguese, Mandarin and Cantonese.

Pricing: Suno's free plan gives 50 credits a day; a third-party review reports one Speech generation (two takes) costs about 10 credits, the same as a song; the free plan allows 7 lifetime trial downloads and carries no commercial rights. Pro is $10/mo ($8 annual) and Premier $30/mo ($24 annual), with 20 and 60 downloads per month respectively. ElevenLabs' free plan gives 10,000 credits a month (about 10 minutes of speech), attribution required, non-commercial; Starter at $6/mo adds a commercial license, Creator is $22/mo, Pro $99/mo.

Features: Suno Speech's differentiator is one-pass generation — narration and an original score mixed into a single track, removing a post-production mixing step — but the company has published no supported-language list, no voice cloning and no API; its announcement admits beta flaws: British accents may drift toward Australian, and dramatic pauses may run long. Eleven v4's differentiator is control — stackable in-sentence tags, International Phonetic Alphabet pronunciation support, instant voice cloning from about 10 seconds of audio, and v4 Turbo's median inference latency of about 100 ms with streaming audio as the upstream LLM generates; a third-party leaderboard snapshot puts v4 Turbo at Elo 1,334 and v4 at 1,321.
