    ElevenLabs 发布 Eleven v4 与 Eleven v4 Turbo 语音模型

    ElevenLabs 发布 Eleven v4 及其低延迟版本 Eleven v4 Turbo,称其为目前最具情感表现力的文本转语音模型。Eleven v4 在 Artificial Analysis 排名第一,盲测中约 75% 听众更偏好它;Eleven v4 Turbo 面向智能体等低延迟场景,中位推理延迟约 100ms,中位首次发声时间约 150ms。两款模型支持 90 多种语言,可用 [laughs] 等内联标签控制语气与音效,Instant Voice Clones 仅需 10 秒音频,并新增 Professional Voice Clones 支持,现已在 ElevenAgents、ElevenCreative 和 ElevenAPI 上线。

    Artificial Analysis1. Eleven v4 Turbo brings that same technology to low-latency use cases like agents. With a median inference latency of 100ms, it can respond faster than the average pause between two people talking. Both models can generate speech that feels emotive, rather than mechanical. Underlying audio fidelity is also higher across the board, with cleaner, more natural-sounding output. Earlier generations of text-to-speech models can read text aloud, but Eleven v4 provides an emotional

    AI 安全研究员 Ryan Greenblatt:每个 AI 实验室都自认负责任,这正是军备竞赛停不下来的原因

Ember-1 costs the same per token as Kimi K3 on Fireworks: $3.00 input, $0.30 cached input, and $15.00 output per 1M tokens. The savings come entirely from generating fewer tokens. At that output rate, the A/B figures work out to about $0.74
