speaker-detector 0.1.7

A CLI + Web tool for speaker enrollment and identification using SpeechBrain.

23/07/2025 - Lara Whybrow, Creator - Works as far as I can see, but now we have a robust set of tools for training and managing the data and can focus now on refinement and bug fixing.

speaker-detector 🎙️

A lightweight CLI tool for speaker enrollment and voice identification, powered by SpeechBrain.

🔧 Features

• ✅ Enroll speakers from .wav audio
• 🕵️ Identify speakers from audio samples
• 🧠 ECAPA-TDNN embedding-based matching
• 🎛️ Simple, fast command-line interface
• 📁 Clean file storage in ~/.speaker-detector/
• 🔊 Optional --verbose mode for debugging

📦 Installation

Install from TestPyPI:

pip install --index-url https://test.pypi.org/simple/ speaker-detector

When installing packages with a stale requirement file you might need to use:  pip install --break-system-packages soundfile to install on WSL Ubuntu

Run this version with -m module flag if you are contributing and want to run server.py:
python3 -m speaker_detector.server

🚀 Usage

🎙️ Enroll a speaker:

speaker-detector record --enroll Lara

🕵️ Identify a speaker:

speaker-detector record --test

📋 List enrolled speakers:

speaker-detector list

🗂️ Project Structure

~/.speaker-detector/enrollments/ Saved .pt voice embeddings ~/.speaker-detector/recordings/ CLI-recorded .wav audio files

🧹 Clean vs Verbose Mode By default, warnings from speechbrain, torch, etc. are hidden for a clean CLI experience. To enable full logs & deprecation warnings:

speaker-detector --verbose identify samples/test_sample.wav

🛠 Requirements Python 3.8+ torch speechbrain numpy soundfile onnxruntime

Step	Command	When / Purpose	Output
1. Export ECAPA Model to ONNX	speaker-detector export-model --pt models/embedding_model.ckpt --out ecapa_model.onnx	Run once unless model changes	ecapa_model.onnx
2. Enroll Speaker	speaker-detector enroll <speaker_id> <audio_path> Example: speaker-detector enroll Lara samples/lara1.wav	Run per new speaker	Individual .pt files (e.g., Lara.pt)
3. Combine Embeddings	speaker-detector combine --folder data/embeddings/ --out data/enrolled_speakers.pt	After enrolling speakers	enrolled_speakers.pt
4. Export Speakers to JSON	speaker-detector export-speaker-json --pt data/enrolled_speakers.pt --out public/speakers.json	For frontend use	speakers.json
5. Identify Speaker	speaker-detector identify samples/test_sample.wav	Identify speaker from audio	Console output: name + score
6. List Enrolled Speakers	speaker-detector list-speakers	Show all enrolled speakers	Console output: list of IDs
Verbose Mode (optional)	Add --verbose to any command: speaker-detector --verbose identify samples/test_sample.wav	Show warnings, detailed logs	Developer debug info

NB: When pushing to Github, do not include any .identifier files.

You can manually clean up stale embeddings that don’t match any existing speaker folder with a quick script:

Run inside your project root

cd storage/embeddings for f in *.pt; do speaker="${f%.pt}" if [ ! -d "../speakers/$speaker" ]; then echo "Deleting stale embedding: $f" rm "$f" fi done
