ElevenLabs
A deep-learning-based speech synthesis company that provides text-to-speech services at near-human quality, capable of capturing subtle characteristics such as intonation, rhythm, and emotion.
Core Facts
ElevenLabs is a company specializing in AI voice and audio synthesis technology, known for its AI dubbing, voice cloning, and text-to-speech services.
Tools such as ElevenLabs' sound effects model and Stability AI's Stable Audio are already capable of generating high-quality ambient sounds and foley effects.
ElevenLabs is an AI voice synthesis company founded in 2022, supporting over 30 languages and capable of cloning voices from very small audio samples
Timeline (last 90 days)
Breeze TTS2 (3.5B parameters), according to the developer's citation, ranks first on the Artificial Analysis leaderboard, surpassing Gemini and ElevenLabs, and is open-weight.
The real-time speech transcription market is still dominated by competitors such as ElevenLabs.
The competitiveness of vendors such as ElevenLabs comes not only from the model itself but also from a complete set of system capabilities including streaming pipelines, endpoint detection and low-latency engineering optimization.
Music and sound effects models reuse the generateSpeech interface, describing the target sound rather than the text to be read aloud in the text field, so callers do not need to learn a new request format, and authentication, billing, retry, and tracing logic remain consistent.
ElevenLabs' speech-to-text models include elevenlabs/scribe-v2 and elevenlabs/scribe-v2-realtime.
Currently all ElevenLabs models on AI Gateway enjoy a 50% discount for the first 14 days, with the promotion running until November 9.
ElevenLabs' music models include elevenlabs/music-v2.5 and elevenlabs/music-v2.
Vercel has partnered with ElevenLabs to bring 14 ElevenLabs audio models into AI Gateway.
In a pipeline-style real-time voice setup, the official example uses Scribe v2 Realtime to transcribe a 16kHz microphone stream, sends the transcribed text to a language model (the example uses anthropic/claude-haiku-5.5), and then feeds the output into speech synthesis.
Developers can use the same AI Gateway API Key to call six categories of ElevenLabs audio capabilities: speech-to-text, streaming speech synthesis, real-time voice agents, music generation, sound effects creation, and multi-voice conversation.

75%VerifiedSpeech synthesis models based on the Transformer architecture, pre-trained on massive multi-speaker corpora, can extract voiceprint features such as timbre, intonation, and rhythm from very short audio clips.
75%VerifiedThe endpoint for ElevenLabs' TTS API is https://api.elevenlabs.io/v1/text-to-speech/{voiceId}, and authentication is performed using the xi-api-key request header.
70%VerifiedElevenLabs' similarity_boost parameter (range 0–1) controls how closely the generated result aligns with the original voice clone sample; values that are too high can sometimes produce artifacts or a degradation in audio quality.
70%VerifiedIn the ElevenLabs TTS API, the stability parameter controls timbre stability, similarity_boost affects the closeness to the original timbre, style adjusts the strength of style, and use_speaker_boost determines whether speaker boost is enabled.
65%Verifiedsimilarity_boost takes effect only in cloning or specified-voice scenarios; the higher the value, the closer the generated speech is to the reference timbre, but when too high it amplifies noise or accent features in the source audio.
65%VerifiedElevenLabs' stability parameter (range 0–1) controls the consistency of generated speech; higher values produce more stable output with less emotional variation, making it suitable for broadcast scenarios.
65%VerifiedElevenLabs v4 supports 90 languages.
65%VerifiedElevenLabs offers a Dubbing API that supports dubbing in 29 languages, with voice cloning capabilities that can preserve the original speaker's timbre and automatically handle background audio separation and retention.
65%VerifiedNeural network TTS models (such as Azure TTS, ElevenLabs, and CosyVoice) can clone a specific speaker's timbre, speech rate, and emotional style using a small amount of reference audio.
