Does this tool transcribe my audio files?

No, it does not transcribe speech or generate text; it only segments and loops the existing audio.

What is the difference between voice-activity and caption mode?

Voice-activity mode automatically detects pauses in speech, while caption mode uses the exact timestamps from your uploaded SRT or WebVTT file.

Can I control how long the silence is between repeated phrases?

Yes, you can adjust the pause duration between 0 and 5 seconds to match your practice pace.

What audio formats are supported for the output?

You can export your final looped practice track as MP3, WAV, FLAC, M4A, or OGG.

What is the maximum file size I can upload?

The tool supports audio files up to 100 MB and caption files up to 10 MB.

Examples

1. Shadowing Practice from a Podcast

Self-taught Language Learner

Background

A student learning Spanish wants to practice shadowing native speakers from a 5-minute podcast episode, but the speech is too fast to repeat in real-time.

Problem

The student needs the podcast broken down into individual phrases, with each phrase repeated 3 times followed by a 2-second pause to allow time to speak.

How to use

Upload the podcast MP3, set the Segment Source to 'Voice activity', set Repetitions to 3, and set the Pause Between Repetitions to 2.0 seconds.

{
  "segmentSource": "voice-activity",
  "repetitions": 3,
  "pauseSeconds": 2.0,
  "outputFormat": "mp3"
}

Outcome

A new MP3 file is generated where each detected Spanish phrase plays three times with a two-second gap in between, allowing the student to shadow the audio easily.

2. Exact Sentence Looping with Subtitles

Language Teacher

Background

A teacher has an audio recording of a French dialogue and a matching SRT subtitle file. They want to create a listening exercise where students hear each exact sentence twice.

Problem

Voice-activity detection might split sentences mid-phrase, so the teacher needs to use the exact subtitle timestamps to segment the audio.

{
  "segmentSource": "captions",
  "repetitions": 2,
  "pauseSeconds": 1.5,
  "outputFormat": "wav"
}
