ElevenLabs launches v4 speech model with 10,000-character limit and Turbo variant

ElevenLabs also introduced Eleven v4 Turbo, a faster variant optimized for real-time voice agents like customer service or game characters. It starts producing speech in 150 milliseconds, compared to 262 ms for Cartesia Sonic 3.6 and 814 ms for OpenAI’s GPT-4o mini TTS. The company claims v4 ranks ahead of competitors on Artificial Analysis’ Provider Voice Arena leaderboard, scoring 91.7% on pronunciation benchmarks—up from 85.6% in v3. Blind tests showed about three-quarters of listeners preferred v4 over models from Cartesia, Inworld, and Google.

Both models launch with temporary pricing cuts: $22 per million characters for v4 (down from $80) and $11 for Turbo (down from $40). Users on the $22 Creator plan or higher can access v4 in ElevenCreative for two weeks at no extra cost, with usage capped at twice their monthly credits. Enterprise customers can store data in isolated EU, India, or Singapore environments, though some processing may occur outside the chosen region.
