AssemblyAI · 异步音视频语音转写API

AssemblyAI官方接口提交可访问的音频或视频URL，使用API key创建异步转写任务，后续可取得文字、词级和说话人等结果。HTTP200只表示入队，不是转写完成。仅文档整理，未上传或转写；模型限制、费用与数据保留未验证。

Source statements below remain in their published language. Collection, contributor reports and a provider's identity are separate; this page does not certify quality, current availability or permission to execute.

Published description

To use our EU server for transcription, replace api.assemblyai.com with api.eu.assemblyai.com. Create a transcript from a media file that is accessible via a URL.

Inputs

audio_url必填，为音频或视频文件URL；可选audio_start_from/audio_end_at以毫秒限制片段。
可选语言与language_detection、speech_models、speaker_labels、多声道、格式、术语及PII处理等，参数有模型和互斥要求。
webhook_url可配置完成/失败通知及认证字段，实际回调会产生外部请求，本轮未配置。

Outputs

提交响应含transcript id与queued/processing等状态，text、words、utterances等在未完成时可为null。
完成后可含识别文字、词时间/置信度、说话人等配置结果；错误可用error/status表达，不保证每项模型功能均有。

Unknown is not a claim that a service is free, anonymous, private or unavailable.

Limitations

200只表示任务创建入队；必须区分completed与error，不能将空text当完成转写。
可选特性依模型/语言，部分旧summarization/auto_chapters参数已deprecated，不把长参数表当所有模型都支持。
PII redaction默认未开启，开启也不等于匿名或零留存；医疗术语模式不是临床准确性保证。
本页没有处理时长、媒体大小、速率、价格或留存政策的完整条件。

Unknowns

实际认证、模型/语言权限、音频限制、价格及速率未知。
数据地域、保留、训练用途、PII准确性和完整隐私条件未验证。
未运行识别、说话人识别、摘要或任何付费模型调用。

Fixed profiles, conditions and evidence

Read state: not_checked; review state: unknown. Do not combine different profiles.

资料与来源声明不等于本站实测；未列出的条件仍未知。

结构化配方只按公开声明检查约束与接口，不执行任务或授予权限；缺失记录保持未知，接口兼容不证明实际成功。
