eSpeak は、英語および他の言語向けのソフトウェア音声合成プログラムです。

eSpeak は、高品質な英語音声を生成します。オープンソースの他のテキスト音声合成 (text to speech - TTS) エンジンとは別の合成手法を使っているため、まったく 異なる音声になります。もしかしたらあまり自然でなかったり、 "滑らか" でないかもしれませんが、発音がはっきりしていて長時間聞きやすいと 感じる方もいます。

コマンドラインプログラムとして実行し、ファイルまたは標準入力からテキストを 与えて発声できます。

  • 様々な声色が含まれます。声の特性は変更できます。
  • 発話結果を WAV ファイルとして出力できます。
  • テキストから音素符号に変換できます。他の音声合成エンジンへの フロントエンドとして組み合わせて使えます。
  • 他の言語への拡張可能性があります。40 以上の言語が含まれます。
  • コンパクトなサイズ。プログラムとデータを含めて約 350 k バイト。
  • C++ で書かれています。

Speech Dispatcher provides a device independent layer for speech synthesis. It supports various software and hardware speech synthesizers as backends and provides a generic layer for synthesizing speech and playing back PCM data via those different backends to applications.

Various high level concepts like enqueueing vs. interrupting speech and application specific user configurations are implemented in a device independent way, therefore freeing the application programmer from having to yet again reinvent the wheel.

This package contains dependencies on packages necessary for running Speech Dispatcher with Festival.

This Text-To-Speech (TTS) engine speaks French; a preliminary English support is also offered. The engine uses context-sensitive rules to produce phonemes from the text. It relies on MBROLA to generate actual audio output from the phonemes. The TTS engine is implemented using the Python programming language.

The upstream authors have come up with this TTS to try and meet their own needs as blind users. It's designed to be plugged as output to some screen-review software, firstly with BRLTTY. They favor speed and intelligibility over perfect pronunciation. Cicero is aimed to have a quick response time, the ability to quickly shut-up and skip to another utterance, intelligibility where it counts (not perfect pronunciation), the ability to track speech progression, relative simplicity (hackability) and relative small code size.

Mbrola is Thierry Dutoit's phonemizer for multilingual speech synthesis. The various diphone databases are distributed on separate packages, but they must be used with and only with Mbrola because of license matters. Read the copyright for details.

Mbrola itself doesn't provide full TTS. It is a speech synthesizer based on the concatenation of diphones. It takes a list of phonemes as input, together with prosodic information (duration of phonemes and a piecewise linear description of pitch), and produces speech samples on 16 bits (linear), at the sampling frequency of the diphone database.

Use Mbrola along with Freephone, cicero or espeak to have a complete text-to-speech in English.
