面向开发者的语音转文字与语音智能 API
文件转写可选异步 API,直播流与语音客服可用实时 API,短音频与听写则用同步接口。
在转录文本上叠加摘要、情感、主题识别、PII 脱敏、内容审核与安全护栏,无需自建模型。
AssemblyAI-TTS-1 基于真实通话数据训练,语音自然、延迟低,面向 IVR 与语音客服场景。
旗舰模型强调精准转写、说话人标注与多语言原生语码混合,并提供公开基准成绩支撑。

首音频低至 50 毫秒的实时语音 AI 接口
文本转语音、语音转文本与实时语音到语音翻译首音频约 50 毫秒,专为对话式智能体而优化,而非批处理场景。
可用短样本快速克隆音色,也可选择生产级专业克隆,或仅凭文字描述生成全新声音。
WebSocket 流式传输、Python 与 Rust SDK、自定义词表、语义化 VAD 和语码切换,让智能体开发者易于集成。
Phonon 是 Gradium 开放可用的 TTS 模型,可端侧运行,适用于离线或隐私敏感部署。
