Get audio output directly

[jhoelzl]

Hello,

i have following code:

text = "Hello, my name is Josef."
targetLanguage = 'de'
tts = gTTS(text, targetLanguage)  
tts.save("synthesized.mp3")

Since i play the output directly after this code, is there a way to get the audio output directly as a variable? So i do not have to save and open the mp3 file again.

Thanks!
Josef

Yes it's possible. You need a module that will play from a file-like/file object. Instead of doing tts.save() you can use tts.write_to_fp() to write to a file-like object that you can then reuse to play. As a really simple example:

from gtts import gTTS
from tempfile import TemporaryFile
tts = gTTS(text='Hello', lang='en')
f = TemporaryFile()
tts.write_to_fp(f)
# Play f
f.close()

This would indeed be fantastic.

I'm having issues with finding a decent approach. Most audio playback libraries are hectic to use in this scanario.

[jhoelzl]

@pndurette thanks for help! Before, i used

os.system('cvlc --play-and-exit ' + "synthesized.mp3")

to play the audio file. Now, i have a an audio object called f.

I tried
os.system('cvlc --play-and-exit ' + f)

but is does not work. Do you have another example how to playback the generated audio object?

Thanks for helping!

Try Pyglet - a multimedia and windowing library for Python (~3MB)

from gtts import gTTS
from time import sleep
import os
import pyglet

tts = gTTS(text='Hello World', lang='en')
filename = '/tmp/temp.mp3'
tts.save(filename)

music = pyglet.media.load(filename, streaming=False)
music.play()

sleep(music.duration) #prevent from killing
os.remove(filename) #remove temperory file

[jhoelzl]

Thanks @anselm94, but i want to avoid saving the audio data on the file system. Instead, i directly want to play the audio output from module gTTS. Do you think this is possible with pyglet?

[anselm94]

Currently Pyglet doesn't support using file-like objects. As the project documentation here (see Loading Media section) says

Future versions of pyglet will also support reading from arbitrary file-like objects, however a valid filename must currently be given.

@jhoelzl
Having the same issue. Have you found the solution yet.

[jhoelzl]

@rishabhrkaushik unfortunately not.

[Khoa-NT]

Hi, are there any ways to output file.wav , not mp3 ? i don't know how to use python play mp3 file.

The pyglet like anselm94 said can't open file .mp3

thank you and regards

[common83]

@shaolinkhoa using pyMedia lib
here example:
https://github.com/common83/playmp3/blob/master/tts_play.py

[AllenAkhaumere]

Use pygame multimedia package

[AllenAkhaumere]

pygame.mixer.init()
pygame.mixer.music.load(file.mp3)
pygame.mixer.music.play()
It works in real-time. Good luck

My solution to unicode-charactered languages:

#!/usr/bin/env python
#-*- coding: utf-8 -*-

from gtts import gTTS
import os

class Speech(object):
	def __init__(self):
		while True:
			try:
				a = raw_input("What you want me to say: ")
				a = unicode(a, "utf-8")
				tts = gTTS(text=a, lang="en")
				
				testfile = "/tmp/temp.mp3"
				tts.save(testfile)

				os.system("mpg123 /tmp/temp.mp3")
				os.system("clear")
				os.system("rm %s" %(testfile))
			except UnicodeDecodeError:
				print "Some characters are not supported."
spc = Speech()

You have to have a mpg123 to run this program, but it deletes the ".mp3" file everytime it finishes the phrase.

@yagiz190799

jesus... rm via os.system() really??? os.unlink() dude!

Also your clear can be safer with print "\033[H\033[J"

Might i also recommend pep8 standard, your using tabs for indentation (smh)... spaces mate!!

some people just want to see the world burn :P

[patel33hardik]

If are you using a web browser,
-save .mp3 to the temp folder on the server
-return file path or name

• use jQuery and HTML
  var file_name = response['Data']; var audio = new Audio(); audio.src = "frontend/temp_mp3/"+file_name; audio.addEventListener("loadedmetadata", function(_event) { var duration = (audio.duration * 1000); audio.play(); $("#TextToAudio").attr("src","frontend/images/text_to_audio_icon.gif"); deleteAudioFile(file_name) setTimeout(function(){ document.getElementById('TextToAudio').disabled=false; $("#TextToAudio").attr("src","frontend/images/text_to_audio_icon.png"); }, duration); });
• after content download, delete file from the server using ajax request.

[themdrizwanansari]

guys use playsound() with NamedTemporaryFile() from tempfile

it works but I fail to see significant decrease in delay in output.

If pygame is not a necessity you all can try to use this solution.

Hello everyone, I would like to share this solution using pyglet which was the only nice way I could resolve this without writing to disk:

import io
import time

import pyglet
from gtts import gTTS

pyglet.options["audio"] = ("pulse",)
TICK = .1

def speak(words: str, lang: str="en"):
    with io.BytesIO() as f:
        gTTS(text=words, lang=lang).write_to_fp(f)
        f.seek(0)
        sound = pyglet.media.load("_.mp3", file=f)
    player = sound.play()
    while player.playing:
        pyglet.app.platform_event_loop.dispatch_posted_events()
        pyglet.clock.tick()
        time.sleep(TICK)

Edit: Improved using suggestions by @VeNoMouS

Hello everyone, I would like to share this solution using pyglet which was the only nice way I could resolve this without writing to disk:

import io
import time

import pyglet
from gtts import gTTS

pyglet.options["audio"] = ("pulse",)
TICK = 0.2

def speak(words: str, lang: str="en"):
    with io.BytesIO() as f:
        gTTS(text=words, lang=lang).write_to_fp(f)
        f.seek(0)
        sound = pyglet.media.load("_.mp3", file=f)
    player = sound.play()
    playtime = player.source.duration
    while (playtime - TICK) > -
        pyglet.app.platform_event_loop.dispatch_posted_events()
        pyglet.clock.tick()
        playtime -= TICK
        time.sleep(TICK)

Would it not make more sense to do the following..

import io
import time

import pyglet
from gtts import gTTS

pyglet.options["audio"] = ("pulse",)

def speak(words: str, lang: str="en"):
    with io.BytesIO() as f:
        gTTS(text=words, lang=lang).write_to_fp(f)
        f.seek(0)
        
        player = pyglet.media.load('_.mp3', file=f).play()
        while player.source.duration != player.time:
            pyglet.app.platform_event_loop.dispatch_posted_events()
            pyglet.clock.tick()

Or better yet...

import io
import time

import pyglet
from gtts import gTTS

pyglet.options["audio"] = ("pulse",)

def speak(words: str, lang: str="en"):
    with io.BytesIO() as f:
        gTTS(text=words, lang=lang).write_to_fp(f)
        f.seek(0)
        
        player = pyglet.media.load('_.mp3', file=f).play()
        while player.playing:
            pyglet.app.platform_event_loop.dispatch_posted_events()
            pyglet.clock.tick()

[sorenmulli]

@VeNoMouS, that definitely looks nicer, but I can't get it to work: I only get the first small snippet of sound and only when i use dispatch_posted_events(), I get a satisfying result.

[VeNoMouS]

@sorenmulli updated those examples for you then ;P

Hey guys im trying to do a voice assistant

HELP

im trying to make the python file speak what i actually want it to speak. I have tried play sound and the temporary files. NO PIGLET or pygame plz

code:

def speak(text): speaker = gTTS(text = text, lang = "en") speaker.save("Voice.mp3") playsound.playsound("voice.mp3")

[themdrizwanansari]

@fasterastv2, do you have read access to the location where Voice.mp3 is being saved?

[SG-SakethGupta]

@themdrizwanansari Just realise that the problem isnt with playing sound.

The actual problem is with the saving part. The line speaker.save("Voice.mp3") causes the problem

[venzen]

Here is a solution to play gTTS sound directly using playsound and NamedTemporaryFile:

from gtts import gTTS
from tempfile import NamedTemporaryFile
from playsound import playsound

def speak(txt, lang='en'):
    gTTS(text=txt, lang=lang).write_to_fp(voice := NamedTemporaryFile())
    playsound(voice.name)
    voice.close()

txt = "Spank me, Daddy"
speak(txt)

Works in Python 3.9 and negates the need to save output to mp3.

[chajiuqqq]

@venzen ,thanks for your solution, only it works for me!

from gtts import gTTS
from tempfile import NamedTemporaryFile
from playsound import playsound

def speak(txt, lang='en'):
    gTTS(text=txt, lang=lang).write_to_fp(voice := NamedTemporaryFile())
    playsound(voice.name)
    voice.close()

txt = "Spank me, Daddy"
speak(txt)

Ohh, my hands hurt.

[EyesOfSiva]

tank you @venzen and @GrimPixel that worked like a charm

[Vuizur]

I tried pyglet, pygame and the tempfile + playsound solution, but they all failed due to various bugs (Windows 10 Python 3.10). Audio play doesn't seem to be a very stable area, seriously, or my PC is broken.

Then I tried this solution:

from io import BytesIO
from pydub import AudioSegment
from pydub.playback import play

def say(text, lang = "en"):
    tts = gTTS(text=text, lang=lang)
    fp = BytesIO()
    tts.write_to_fp(fp)
    fp.seek(0)
    song = AudioSegment.from_file(fp, format="mp3")
    play(song)

which in theory should be efficient because it avoids writing the file on disk. Or so I thought, but it ended up being a few hundred ms slower than the naive solution which simply writes the file to disk. (I have an SSD though.) For a short text (5 words) the solution below is 200 - 300 ms faster.

from playsound import playsound

def speak_gtts(words: str, lang: str="en"):
    filename = datetime.now().strftime("%Y-%m-%d_%H-%M-%S") + ".mp3"
    tts = gTTS(words, lang=lang)
    tts.save(filename)
    playsound(filename)
    os.remove(filename)

[SohaybSebaa]

from tempfile import NamedTemporaryFile
from playsound import playsound

def speak(txt, lang='en'):
    gTTS(text=txt, lang=lang).write_to_fp(voice := NamedTemporaryFile())
    playsound(voice.name)
    voice.close()

txt = "wow"
speak(txt)```

playsound is relying on another python subprocess. Please use `pip install pygobject` if you want playsound to run more efficiently.`
