SpeakTrigger: AI Auto Recorder

SpeakTrigger is a smart recording app that automatically starts recording once it detects a human voice. Unlike traditional voice-activated recorders that rely on simple volume thresholds, this app uses AI trained on voice characteristics to detect speech naturally. It ignores background noise and most non-configured audio, so the recording focuses only on meaningful human conversations.

⭐ Why It’s Smarter
AI Voice Trigger: Records based on voice characteristics rather than volume, focusing on speech and skipping most other sounds.
Continuous Recording: Automatically skips silence and most non-speech segments, making long recordings more efficient and reducing storage usage.
Efficiency in Long Sessions: Extended recordings benefit most from capturing only active voice, saving time during review and playback.
Works Anytime, Anywhere: Suitable for voice memos, meetings, classrooms, and long-duration or quiet sleeping environments.


🎯 Ideal Use Cases

• Voice Notes
Records only active speech over extended periods, perfect for note-taking.

• Sleep Talking
Automatically detects and records speech during sleep, capturing only voice-related sounds. Silence, most snoring, and most background noise are automatically skipped.
A small amount of speech-like snoring may be included to avoid missing real sleep talking. Lowering sensitivity can reduce snoring recordings.

• Anywhere Voice-to-Text
Records only active speech, minimizing conversion costs.

• Meetings and Lectures
Automatically records presentations, discussions, and Q&A sessions.

• Classroom
Records teacher presentations and student questions without manual intervention.

⚙️ Key Features

Continuous Long-Term Recording
All detected and selected voice content is saved in a single file, skipping silence and most non-configured audio.

Pre-Recording Buffer
To avoid missing the beginning of important audio events, the app maintains a short in-memory pre-recording buffer while recording is active. When a configured event is detected, a brief portion of buffered audio may be included to provide context. This buffer is temporary and is only written to storage when a valid recording event occurs.

Continuous Playback
Supports long-term background playback for uninterrupted listening.

Storage Protection
Multiple protections prevent recording loss, including automatic saving in the event of low battery, system limitations, or low storage capacity.

Recording Recovery
If recording is interrupted unexpectedly, any unsaved audio data will be automatically restored the next time recording is started.
On devices that support automatic service restart, recording may resume automatically after interruption. Recovered recordings are clearly identified through their file names.

User-Friendly Interface
Simple start/stop control with minimal setup.

Directory Management and File Sharing
Easily manage directories and share recordings.

Day/Night Themes
A comfortable interface for any lighting condition.

SpeakTrigger records only what matters, skipping silence and most background noise, and all detection and processing are done locally, keeping your recordings private while letting you focus on the moment.

💤 Sleep Talking Tip
Some snoring that sounds like speech may be recorded to avoid missing sleep talking. Lowering the sensitivity will reduce these speech-like snoring recordings. The waveform display during playback can help: speech appears irregular, while snoring is usually more rhythmic and regular.
