This feels like it should be a RefPtr<StorageErrorCallback>&& that is WTFMoved into the lambda so we are sure there is still a reference when we call the callback.  Otherwise, it's not obvious that there couldn't be a use after free.

This should definitely be a PlatformSpeechSynthesisUtterance&

> Source/WebCore/Modules/speech/SpeechSynthesis.cpp:209
> +void SpeechSynthesis::didStartSpeaking(PlatformSpeechSynthesisUtterance* utterance)

ditto

> Source/WebCore/Modules/speech/SpeechSynthesis.cpp:215
> +void SpeechSynthesis::didPauseSpeaking(PlatformSpeechSynthesisUtterance* utterance)

ditto

> Source/WebCore/Modules/speech/SpeechSynthesis.cpp:235
> +void SpeechSynthesis::speakingErrorOccurred(PlatformSpeechSynthesisUtterance* utterance)

etc.

> Source/WebCore/Modules/speech/SpeechSynthesisVoice.h:53
>      RefPtr<PlatformSpeechSynthesisVoice> m_platformVoice;

This should be made a Ref.

This should be a PlatformSpeechSynthesisVoice&.  PlatformSpeechSynthesizer.m_voiceList should be Refs.
