Examples

### Direct TTS Audio Output

First, import the ESpeakNG engine wrapper:

from espeakng import ESpeakNG

now for some simple direct TTS output:

esng = ESpeakNG() esng.say(‘Hello World!’)

lower pitch and speed:

esng.pitch = 32 esng.speed = 150 esng.say(‘Hello World!’)

try a different language:

esng.voice = ‘german’ esng.say(‘Hallo Welt!’)

specify phonemes instead of words:

esng.voice = ‘english-us’ esng.say(“[[h@l’oU w’3:ld]]”)

### Synthesize Wave File without Playing It

>From Text:

import wave import StringIO

esng.voice = ‘english-us’ wavs = esng.synth_wav(‘Hello World!’) wav = wave.open(StringIO.StringIO(wavs)) print wav.getnchannels(), wav.getframerate(), wav.getnframes()

result:

1 22050 24210

### List Available Voices

l = esng.voices

result:

>>> l[0]
{'pty': '5', 'language': 'af', 'gender': 'M', 'age': '--', 'voice_name': 'afrikaans', 'file': 'gmw/af'}
>>> l[1]
{'pty': '5', 'language': 'am', 'gender': '-', 'age': '--', 'voice_name': 'amharic', 'file': 'sem/am'}
>>> l[2]
{'pty': '5', 'language': 'an', 'gender': 'M', 'age': '--', 'voice_name': 'aragonese', 'file': 'roa/an'}
...

### Grapheme to Phoneme (G2P) Conversion

ipa = esng.g2p (‘Hello World!’, ipa=2)

result:

>>> print ipa
həlˈo͡ʊ wˈɜːld
