# Audio Speaker Turn Detector Mark likely acoustic turn changes in speech-range audio and export an approximate turn timeline. > Canonical page: https://elysiatools.com/en/tools/audio-speaker-turn-detector - **Category:** Media - **Keywords:** speaker turn, diarization, voice change, audio timeline ## Overview This deterministic analysis compares adjacent speech windows by spectral balance, zero-crossing rate, and level. It identifies acoustic changes that can help with editing and review, but it does not identify people, perform speaker diarization, or prove that every marker is a speaker change. ## Inputs - **Audio File** (file): Select dialogue or interview audio - **Sensitivity** (select) - **Minimum Turn (s)** (number) - **Export Format** (select) ## When to use - When you need to segment a raw interview or podcast recording into distinct conversational turns before editing. - When preparing audio files for transcription and you want to pre-mark timestamps where the speaker changes. - When analyzing dialogue recordings to map out the pacing and frequency of speaker transitions. ## How it works - Upload your dialogue or interview audio file in a supported audio format. - Adjust the detection sensitivity and set the minimum duration in seconds for a valid speaker turn. - Choose your preferred export format, such as JSON, CSV, or SRT. - Run the analysis to process the audio and download the generated timeline of acoustic turn changes. ## Use cases - Segmenting podcast episodes to quickly locate and edit transitions between the host and guests. - Generating SRT subtitle templates with pre-placed time blocks for manual transcription. - Analyzing raw research interviews to map out conversational turn-taking dynamics. ## Frequently asked questions ### Does this tool identify who is speaking? No, it only detects acoustic changes between adjacent speech windows and does not perform speaker identification or diarization. ### What file formats can I export the timeline in? You can export the speaker turn timeline as a JSON file, a CSV table, or SRT subtitle markers. ### How does the sensitivity setting affect the results? The 'Sensitive' option detects minor acoustic shifts but may cause false positives, while 'Conservative' only flags major changes, reducing false triggers. ### Can I set a minimum duration for each speaker turn? Yes, you can configure the minimum turn duration between 0.2 and 30 seconds to filter out short interruptions or noise. ### Is this tool using AI to transcribe the audio? No, it uses deterministic acoustic analysis based on spectral balance, zero-crossing rate, and signal level, without transcribing text. ## Related tools - [Audio Kick-Bass Phase Aligner](https://elysiatools.com/en/tools/audio-kick-bass-phase-aligner): Compare kick and bass timing/phase in the low band, report the offset and polarity, and export the corrected track with sample-accurate alignment. - [Audio Remote Guest Rescue](https://elysiatools.com/en/tools/audio-remote-guest-rescue): Reduce room echo, broadband noise, boxiness, and dullness in remote guest recordings. - [Audio Voice Activity Segmentation](https://elysiatools.com/en/tools/audio-voice-activity-segmentation): Detect likely speech-range activity and export speech/non-speech ranges as JSON, CSV, SRT markers, or an FFmpeg cut list. - [Audio Clipping Region Exporter](https://elysiatools.com/en/tools/audio-clipping-region-exporter): Detect digital clipping and export timecoded flat-top regions for de-clipper repair or editorial notes. - [Audio Insert Silence](https://elysiatools.com/en/tools/audio-insert-silence): Insert silence at a specific timestamp in an audio file - [Audio Interview Level Matcher](https://elysiatools.com/en/tools/audio-interview-level-matcher): Match loudness between a host and a guest track (or any two voice takes) while preserving natural dynamics. - [Audio Key Change for Singers](https://elysiatools.com/en/tools/audio-key-change-for-singers): Transpose a song by key or semitones while preserving its duration and speed. - [Audio Mouth Click Finder](https://elysiatools.com/en/tools/audio-mouth-click-finder): Detect-style repair for lip smacks, saliva clicks, mouth ticks, and small voice-over clicks. ## Samples - [Copyright-Free FLAC Audio Samples](https://elysiatools.com/en/samples/flac-samples): Lossless FLAC audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Copyright-Free MP3 Audio Samples](https://elysiatools.com/en/samples/mp3-samples): Collection of royalty-free audio samples for testing and development purposes including nature sounds, meditation music, and ambient audio - [Copyright-Free WAV Audio Samples](https://elysiatools.com/en/samples/wav-samples): Uncompressed PCM WAV audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Speech Learning & Safety Audio Samples](https://elysiatools.com/en/samples/audio-learning-safety-samples): Deterministic synthetic WAV inputs for pronunciation comparison, dictation preflight, alert degradation, and voice privacy tools. ## Related content - [Podcast Recording, Editing, and Delivery](https://elysiatools.com/en/hubs/podcast-recording-editing-delivery): Rescue remote voices, clean speech artifacts, shape the edit, master loudness, add show assets, and validate podcast files before delivery.
