Echo

Echo is a voice-to-text accessibility tool that lets you speak instead of type, inserting your words directly into any app's text field.
Echo is built for people who find typing difficult or painful, including users with motor impairments such as RSI or hand injuries, users with dyslexia or other learning differences who find writing slower than speaking, older users whose typing speed has declined, and anyone facing a temporary situational barrier to typing.
How Echo uses the Accessibility API: Echo uses Android's AccessibilityService API to insert transcribed text directly into the text field you have focused — such as a message box, email, or search bar — so you don't have to switch apps or copy and paste. Echo only writes to the field you have explicitly tapped and confirmed. It does not read, collect, or monitor your screen content, and it does not perform any action without your direct input.
Speak in your own language — Echo transcribes English and Hindi-English speech and works across messaging, email, notes, and browsers.
Echo does not use the Accessibility API to change your settings, work around privacy controls, record calls, or take any action on your behalf beyond inserting the text you dictate.
