Ekho(余音)

简体中文版

(updated on Nov 19, 2009)

eGuideDog TTS (Ekho, 余音) is a text-to-speech (TTS) software. It supports Cantonese, Mandarin and Korean (in trial). It can also speak English through Festival. Unlike eSpeak, Ekho is designed in an simpler way but bigger package size. It may produce more natural voice than eSpeak because it uses human voice.

Here are some demos:

Ekho supports both Linux and windows. We release source and voice data separately. In order to use the voice data, we just need to extract them to the directory under ekho.

Voice data download page: Ekho Voice Data


(Voice files begun with jyutping are for Cantonese while pinyin for Mandarin and hangul for Korean. 44100 and 16000 in the file name means sample rate. Higher sample rate generates higher quality.)

Here is the link to the latest Windows version with 16000Hz voice data of Cantonese, Mandarin: ekho-2.0.exe (38M)
And this is the latest Linux version: ekho-2.0.tar.bz2 (43M)

If you want to use Ekho as a Chinese learning tool, Gradint may be a more suitable choice.

Here is an install guide for Linux: How to install Ekho. If you find it too difficult to build Ekho on Linux, try using the mini version ekho-mini-2.0beta.tar.bz2 (9M), which is pre-built with limited functions but an external OGG player (mplayer, ogg213 or play in sox) is needed.

It's highly appreciated to contribute more voices. To make a new voice, please refer How to make a new voice for Ekho.

If you find the pronunciation of some Cantonese words are not correct, it would be kind to tell us. Please refer mission 2 of Cantonese Dictionary for detail.
