# Steps to reproduce

1. Open https://eeejay.github.io/webspeechdemos/

# Expected behavior

"kyoko (ja-JP)" is listed on the voice pulldown.

# Actual behavior

"Kyoko (ja-JP)" is not listed on iOS 16.0.2 or later. iOS 16.0 or below seem work well.

Note that the Japanese text still can be spoken on iOS 16.0.2 though there are no Japanese voice.

I couldn't confirm on my device but my colleague says that enabling VoiceOver sometimes solves the issue. 

SpeechSynthesis is widely used for accessibility feature of educational textbook in Japan. This bug breaks at least two reading systems. I'm expecting the fix. Thanks.

Ack'd. There were no changes in 16.0.2 that would have caused this, so possible it's intermittent. We'll investigate
