问题
Basically what i want is TTS in python 3... I already tried pyttsx but aparently it only works with python 2 I already tried other things too... Now i'm trying with the api from voicerss.org but i can't figure out how can HTTP GET it and then play it with python with pyglet...
here is my code so far:
import pyglet
import urllib3
http = urllib3.PoolManager()
speechrequest = http.request('GET', 'http://api.voicerss.org/?key=04f49802d32d442ca997d4d2ea76d3d5&hl=pt-pt&c=wav&src=texto')
speech = pyglet.media.load(speechrequest)
speech.play()
pyglet.app.run()
The errors are:
Traceback (most recent call last):
File "C:/Users/Diogo/Documents/test.py", line 6, in <module>
speech = pyglet.media.load(speechrequest)
File "C:\Users\Diogo\AppData\Local\Programs\Python\Python35\lib\site-packages\pyglet\media\__init__.py", line 1429, in load
source = get_source_loader().load(filename, file)
File "C:\Users\Diogo\AppData\Local\Programs\Python\Python35\lib\site-packages\pyglet\media\__init__.py", line 1410, in load
return riff.WaveSource(filename, file)
File "C:\Users\Diogo\AppData\Local\Programs\Python\Python35\lib\site-packages\pyglet\media\riff.py", line 185, in __init__
file = open(filename, 'rb')
TypeError: invalid file: <urllib3.response.HTTPResponse object at 0x0000002EB0730D30>
i guess its not returning an wav file to python don't know why because. If i enter 'http://api.voicerss.org/?key=04f49802d32d442ca997d4d2ea76d3d5&hl=pt-pt&c=wav&src=texto' in internet explorer it returns a wav file...
So, my questions are:
what i am doing wrong with the code or if is impossible this way how can python speak?
Please be patient with me, i'm only 18 years old and i can't speak english properly, because i'm portuguese...

You could save the remote wav file locally and play it using a default application:
#!/usr/bin/env python3
from urllib.request import urlretrieve
import webbrowser
filename = 'speech.wav'
urlretrieve("http://api.voicerss.org/?key=04f49802d32d442ca997d4d2ea76d3d5"
"&hl=pt-pt&c=wav&src=texto", filename)
webbrowser.open(filename) # play the file using default application
On Windows, you could use os.startfile()
instead of webbrowser.open()
or to play the wav file directly in Python without an external application:
import winsound
winsound.PlaySound('speech.wav', winsound.SND_FILENAME)
Your code have at least two issues:
- You should pass a filename (a string) to
pyglet.media.load()
function, not anHTTPResponse
object. pyglet
may fail to play it anyway: I getpyglet.media.riff.RIFFFormatException: Size of format chunk is incorrect.
error on my system.
You could also play a remote wav file without saving it to disk i.e., you can play streaming content:
#!/usr/bin/env python3
from urllib.parse import quote
from urllib.request import urlopen
api_key = open('api.key', encoding='ascii').read().strip()
language = 'pt-pt'
text = quote("1 2 3")
playwav(urlopen('https://api.voicerss.org/?c=wav&f=8khz_8bit_mono&ssml=false&'
'key={api_key}&src={text}&hl={language}'.format(**vars())))
where playwav()
:
import wave
from contextlib import closing
import pyaudio # Windows: py -m pip install pyaudio
# $ sudo apt-get install python{,3}-pyaudio
player = None
def playwav(path_or_file):
global player
if player is None:
player = pyaudio.PyAudio()
with closing(wave.open(path_or_file, 'rb')) as wavfile, \
closing(player.open(
format=player.get_format_from_width(wavfile.getsampwidth()),
channels=wavfile.getnchannels(),
rate=wavfile.getframerate(),
output=True)) as stream:
while True:
data = wavfile.readframes(1024) # read 1024 frames at once
if not data: # EOF
break
stream.write(data)
