espeak和mbrola

eSpeak is a compact open source software speech synthesizer for English and other languages, for Linux and Windows. http://espeak.sourceforge.net

espeak是语音合成工具。mbrola是语音文件。从text到phoneme转换由espeak完成。而从音素到sound由mbrola完成。

如果想使用espeak作为语音合成工具。可以使用-v 选项来选择mbrola volice文件。此时就需要提前安装好mbrola volice

espeak 源码安装方法：  Linux中文朗读软件--espeak  http://blog.csdn.net/derryzhang/article/details/5769267

 试试中文发音
$ espeak -vzh “hello world”
$ espeak -vzh “你好”

使用mbrola voice:

If you use the eSpeak voice such as "mb-en1" then eSpeak will use the mbrola "en1" voice, eg:
espeak -v mb-en1 "Hello world"

To generate mbrola phoneme data (.pho file) you can use:
espeak -v mb-en1 -q --pho "Hello world"
or
espeak -v mb-en1 -q --pho --phonout=out.pho "Hello world"

Victory!!! Launched your package neo_voice, it works!!! But I have a problem with neo_talk: I downloaded
http://tcts.fpms.ac.be/synthesis/
and unzipped en1.
Then run
mbrola en1 euler.pho euler.wav

but
Error with euler.pho input file !
and when ran
rosservice call /say "hello"

solution：try to install mbrola and voices packages with synaptic (ubuntu softwares)

安装成功后voice位于/usr/share/mbrola/en1

neo_talk$ mbrola -h

 USAGE: mbrola [COMMAND LINE OPTIONS] database pho_file+ output_file

A - instead of pho_file or output_file means stdin or stdout

Extension of output_file ( raw, au, wav, aiff ) tells the wanted audio format

MBROLA VOICES

---

The Mbrola project is a collection of diphone voices for speech synthesis. They do not include any text-to-phoneme translation, so this must be done by another program. The Mbrola voices are cost-free but are not open source. They are available from the Mbrola website at:

http://www.tcts.fpms.ac.be/synthesis/mbrola/mbrcopybin.html

eSpeak can be used as a front-end to Mbrola. It provides the spelling-to-phoneme translation and intonation, which Mbrola then uses to generate speech sound.

neo_talk$ cat readme

# This is a Espeak wrapper for QBO robot from THE CORPORA

# It uses Mbrola to produce nice voice.

# Actually it's in French, but it's easy to change :

#    download your model voices, and change "fr_speak" line content to feet your need

#       ( replace "fr1" by "en" or "es"....)

#

Open a terminal :

sudo apt-get install espeak

sudo apt-get install mbrola

search on web for mbrola voices, you have very good voices english, spanish, french... Quite better than festival

this node creates a service called "/say"

 When neo_talk is running, you can make QBO speak with this, in terminal command : rosservice call /say "Salut a tous"

Enjoy
