Generated config is not useable by firefox & derivetives

[VoidAndCaffeine]

When using the auto-generated config, Firefox (and derivatives such as Zen) does not present the headphone icon in reader view, and websites using the system speech API fail to play.
For some reason changing piper.conf from this:

GenericExecuteSynth "if command -v sox > /dev/null; then\
        PROCESS=\'sox -r 22050 -c 1 -b 16 -e signed-integer -t raw - -t wav - tempo $RATE pitch $PITCH norm\';\
        if command -v paplay > /dev/null; then\
            OUTPUT=\'$PLAY_COMMAND\';\
        else\
            OUTPUT=\'aplay\';\
        fi;\
    elif command -v paplay > /dev/null; then\
        PROCESS=\'cat\'; OUTPUT=\'$PLAY_COMMAND --raw --channels 1 --rate 22050\';\
    else\
        PROCESS=\'cat\'; OUTPUT=\'aplay -t raw -c 1 -r 22050 -f S16_LE\';\
    fi;\
    echo \'$DATA\' | /home/azalea/.var/app/com.mikeasoft.pied/data/pied/piper/piper --model /home/azalea/.var/app/com.mikeasoft.pied/data/pied/models/en_US-amy-medium.onnx -s 0 --output_raw | $PROCESS | $OUTPUT;"
GenericRateAdd 1
GenericPitchAdd 1
GenericVolumeAdd 1
GenericRateMultiply 1
GenericPitchMultiply 1000
AddVoice "en_US" "MALE1" "Piper"

to this:

GenericExecuteSynth "if command -v sox > /dev/null; then\
        PROCESS=\'sox -r 22050 -c 1 -b 16 -e signed-integer -t raw - -t wav - tempo $RATE pitch $PITCH norm\';\
        if command -v paplay > /dev/null; then\
            OUTPUT=\'$PLAY_COMMAND\';\
        else\
            OUTPUT=\'aplay\';\
        fi;\
    elif command -v paplay > /dev/null; then\
        PROCESS=\'cat\'; OUTPUT=\'$PLAY_COMMAND --raw --channels 1 --rate 22050\';\
    else\
        PROCESS=\'cat\'; OUTPUT=\'aplay -t raw -c 1 -r 22050 -f S16_LE\';\
    fi;\
    echo \'$DATA\' | /home/azalea/.var/app/com.mikeasoft.pied/data/pied/piper/piper --model /home/azalea/.var/app/com.mikeasoft.pied/data/pied/models/$VOICE -s 0 --output_raw | $PROCESS | $OUTPUT;"
GenericRateAdd 1
GenericPitchAdd 1
GenericVolumeAdd 1
GenericRateMultiply 1
GenericPitchMultiply 1000
AddVoice "en-US" "female1" "en_US-amy-medium.onnx"
DefaultVoice "en_US-amy-medium.onnx"

fixes the problem. I would submit a pr myself but I don't have the time to find the code that generates the config.

Seems to be a duplicate of #23

A workaround is possible #23 (comment)

Your fix seems better than using this workaround

The template is here

pied/lib/templates.dart

Line 23 in 94f9024

AddVoice "LANGUAGE" "MALE1" "Piper"

And will probably need to replace the selected voice

pied/lib/voice_buttons.dart

Line 173 in 94f9024

configString = configString.replaceAll("MODEL_PATH",
