espeak

Text to phoneme conversion, powered by espeak-ng.

The native library compiles automatically via Dart Native Assets (requires a C compiler).

Usage

import 'package:espeak/espeak.dart';

final espeak = Espeak.init('./espeak-data');
final phonemes = espeak.phonemize('Hello world');
print(phonemes); // həlˈoʊ wˈɜːld
espeak.dispose();

Phoneme Data

espeak needs compiled phoneme data at runtime. Add espeak as a dependency and run the compiler:

dart run espeak:compile_data --all --exclude=fo --output ./espeak-data

Then pass the output path to Espeak.init().

Note: espeak_cli is also available but dart pub global activate doesn't support native assets yet. Use dart run from a project that depends on espeak instead.
