I am using Web Speech API for TTS in my javascript desktop app on Chrome (latest version) on Windows 10 Home Edition. It worked well before but a weird thing happens recently: I have configured to use 'Google UK English Female' but at random a male voice comes out during the conversation though the SpeechSynthesisVoice's debug output shows 'Google UK English Female'.
I searched around and tried various things but still hears the strange male voice intermittently, not very often though.
I've found a post that has the same issue, there is no answer in that post:
Chrome TTS Voice Alternates Between Female and Male.
Any helps will be greatly appreciated!
