Why espeak-ng sounds really bad in stretch

[alfaktulu]

Hi everyone.

 

I have a opz with H2+ and expansión board. I had installed Jessie before. And now, I upgraded to stretch. 

 

why espeak-ng sounds so bad??

 

in jessie that did not happen.

which voice and speed parameters do you use?

I cant find a difference - on my OPi Zero - in the sound to my other systems for the default voice I do use.

 

I do use a little speak.sh script to get around the on/off of the amplifier:

# put text into file
echo $* > /tmp/speak_this.txt

# generate short empty wav-file
espeak-ng ""  -w /tmp/empty.wav -s145

# generate wav file for the text - speed 145 voice english
espeak-ng -f /tmp/speak_this.txt -w /tmp/espeak.wav -s145 -ven

# play the short empty file to activate the amplifier
aplay -D plughw:0,0 /tmp/empty.wav 2>/dev/null

# wait 2 seconds
sleep 2

# play the text wave file
aplay -D plughw:0,0 /tmp/espeak.wav 2>/dev/null

# cleanup
rm /tmp/espeak.wav
rm /tmp/speak_this.txt

@alfaktulu I checked my other OPi Zero and found that there Iam using a mbrola-voice with espeak which sounds better

 

Because Iam a german guy I do use the mbrola-de6  (German male voice for Mbrola) voice via the command:
 

espeak  -vgerman-mbrola-6 -f /home/guido/speak.txt -w /tmp/espeak.wav -s110; aplay -D plughw:0,0 /tmp/espeak.wav 2>/dev/null; rm /home/guido/speak.txt

german-mbrola-6 is installed via apt as package mbrola-de6

For using mbrola-voices you have to install mbrola and the voice you want to use.

You cant find these voice packages with

apt-cache search 'mbrola-'

this will give you a "long" list:
