Text-to-speech (TTS) module that works under Pytho

问题:

I have tried PyTTS (deprecated) and PyTTSx (the most recommended) and two Google TTS solutions (gTTS and another one by some guy named Hung Truong) but none of them worked under Python 3.4. It seems they haven't been ported to 3.x.

I searched here on StackOverflow and Google, but all the proposed TTS solutions don't work under Python 3. I'm on Windows 7.

A user on Reddit found a solution.

Turns out that gTTS works under Python 3.x, it was me that was importing the module wrong.

I was using:

import gtts
blabla = ("Spoken text")
tts = gTTS(text=blabla, lang='en')
tts.save("C:/test.mp3")

Resulting in the following error:

NameError: name 'gTTS' is not defined

When the correct way is:

from gtts import gTTS
blabla = ("Spoken text")
tts = gTTS(text=blabla, lang='en')
tts.save("C:/test.mp3")

The best solution for that is :

pyttsx3

---

Pyttsx3 is an offline cross-platform Test-to-Speech library which is compatible with both Python 3 and Python 2 and supports multiple TTS engines.

I have found it very useful and there is no delay in sound production unlike gTTS which needs internet connection to work and also has some delay.

To install :

pip install pyttsx3

Here is a sample code :

```

import pyttsx3
engine = pyttsx3.init()
engine.say("Hello this is me talking")
engine.setProperty('rate',120)  #120 words per minute
engine.setProperty('volume',0.9) 
engine.runAndWait()

```

I just installed gtts 1.0.7 that was uploaded on 2015-10-07

The following code works for me in Python 3.5:

import subprocess
from gtts import gTTS

audio_file = "hello.mp3"
tts = gTTS(text="Hello World!", lang="en")
tts.save(audio_file)
return_code = subprocess.call(["afplay", audio_file])

I'm on a Mac using in the inbuilt "afply" to play the mp3 but there are other ways e.g. Playing mp3 song on python

Rather than using a module, you could use Google Text-to-Speech API . You can easily use this URL to generate a wav file and get it through a simple HTTP request:
