21.5 azspeech synthesize
command will generate spoken word audio, spoken by a human sounding
voice, from supplied text, and will play the audio on the system’s
default output audio device. With
--output a wav file can
be specified as the output rather than having the audio played through
$ ml synthesize azspeech [sentence] -i <file.txt> --input=<file.txt> Text to be spoken. -l <lang> --lang=<lang> Target language. -o <file.wav> --output=<file.wav> Save synthesized audio to file. -v <voice> --voice=<voice>
The simplest usage is to synthesise the sentence provided on the command line:
ml synthesize azspeech Welcome my son, welcome to the machine.
The spoken language can be chosen, though this will attempt to pronounce the words as if they are French:
ml synthesize azspeech --lang=fr-FR It's alright, we know where you've been.
Trying another accent:
ml synthesize azspeech --voice=en-AU-NatashaNeural You brought a guitar to punish your ma.
The command can be part of a pipeline:
echo "It's alright, we told you what to dream" | ml synthesize azspeech
The text can be sourced from a file:
ml synthesize azspeech --input=short.txt ml synthesize azspeech --lang=de-DE --input=short.txt ml synthesize azspeech --voice=fr-FR-DeniseNeural --input=short.txt
