Thanks for making the time. I want to start with framing — what was the original hypothesis behind the project?

S2

Honestly, maybe forty percent. The shape held — the mechanics underneath had to be rebuilt almost entirely.

95%+ on clear English. It holds up on real-world recordings too.

Modern transcription reaches 95%+ word accuracy on clear English at 128 kbps and above, comparable to a human transcriber on the same recording. The audio coming in sets the ceiling — cleaner source, cleaner transcript. The breakdown below covers the recordings we actually see in production.

Common questions

6 things people ask about this.

01支持哪些MP3比特率?+
支持所有标准MP3比特率,从32 kbps到320 kbps,包括恒定比特率(CBR)和可变比特率(VBR)。128 kbps及以上准确性最佳。低于64 kbps时,感知压缩开始影响单词准确性——对于此质量的录音,建议进行人工校对。
02先将MP3转换为WAV是否会提高准确性?+
不会。将MP3转换为WAV无法恢复MP3编码过程中丢失的音频信息。如果你有原始WAV或无损格式的录音,直接使用它们可以获得稍好的效果。但128 kbps及以上的标准MP3本身就是极佳的源材料。
03MP3文件的最大大小是多少?+
免费版:每个文件最大100 MB,最长30分钟(以先到者为准)。Pro版:每个文件最大2 GB,最长10小时(128 kbps下约8–9小时)。Business版:每个文件最大5 GB,最长10小时。对于多文件归档,请将每个文件作为单独的API任务提交——Pro版最多支持20个并发任务,Business版最多支持50个。
04可以从MP3中导出SRT文件吗?+
可以。直接从转录页面导出SRT或VTT格式——适用于重新上传字幕到YouTube、在视频编辑中嵌入字幕,或存档带时间戳的转录稿。时间戳与原始MP3中的位置对应。
05转录一个MP3需要多长时间?+
一个60分钟的MP3通常在60–120秒内完成。长文件会分块并行处理——4小时的文件不会增加4倍时间。Business计划任务享受优先处理。
06是否适用于非英语的MP3文件?+
是的——支持100+语言,系统从音频前30秒自动检测。一级语言(英语、西班牙语、德语、法语、葡萄牙语、意大利语、荷兰语、波兰语)在任何标准比特率MP3上均可达到95%以上的准确性。二级语言(俄语、日语、普通话、韩语及其他13种语言)可达到生产级准确性。
