I find that even with the AVSpeechUtterance volume set to the maximum of 1.0, the voice is very quiet compared to, for example, any background music that is playing either in the app itself or externally.
Is there any way to make this any louder?
Is there any solution?
I use AVAudioSession to reduce the volume of music playing in the background.
but, the volume of the voice played by AVSpeechSynthesizer is too quiet, so I want to increase the volume of the voise in some way.
