EdgeEcho: Lock Your Phone, Touch Grass, and Let Edge AI Identify the Wild

Описание и применение

EdgeEcho – офлайн‑приложение‑PWA, которое распознаёт 521 звук природы, используя локальный edge‑AI и TTS, позволяя пользователям оставаться в окружении без экрана.

Задача

Outdoor enthusiasts need a way to identify environmental sounds without pulling out their phone or relying on cellular connectivity.

Результат

EdgeEcho enables hikers and birdwatchers to identify wildlife sounds offline, preserving privacy and eliminating data‑transfer costs.

Рабочий процесс

• 1. Tap "Start Listening" in the EdgeEcho app.
• 2. Lock the phone and place it in the pocket.
• 3. Walk or hike; the app continuously records audio.
• 4. The TensorFlow.js YAMNet model processes the 16kHz mono buffer locally.
• 5. When a sound is classified, offline TTS speaks the result into the earbuds.
• 6. No visual dashboard is shown, keeping the user’s eyes on the environment.
