Any tests or unskip test by this patch ?

ASSERT_NOT_REACHED() ?

Currently only Mac has supported speech synthesis and there're some tests that could be shared. There look generic

There are some tests in Mac, they seem generic and could be shared with other ports. I will add them in the next patch.

This object should never be deleted but just in case having this assert sounds fine with me.

DONE.

Any chance m_platformSpeechWrapper can be null though this is created ctor ?

Isn't ASSERT() better ?

If you want to add tests in next time, I think we should not enable this feature in this time.

It would be good if you place this by alphabet order.

Hmm, probably not

but I'm fine with having this ASSERT, done.

Why we still need to check if m_platformSpeechWrapper is null ? I meant m_platformSpeechWrapper can't be null. So, we don't need to check it. Thus, we can use ASSERT() because m_platformSpeechWrapper should not be null.

Yes, you're right, this can be deleted, sorry. I sometimes find myself too wary.

Why here ?

char -> character ?

> Source/WebCore/platform/efl/PlatformSpeechSynthesisProviderEfl.cpp:93
> +    if (!m_isEngineStarted) {

How about using early return for better readability as below ?

    if (!m_isEngineStarted) {
        if (m_isEngineStarted = espeak_Initialize(AUDIO_OUTPUT_PLAYBACK, 0, 0, 0) == EE_INTERNAL_ERROR)
            return false;
   }
   espeak_SetVoiceByName("default");
  
   return true;

> Source/WebCore/platform/efl/PlatformSpeechSynthesisProviderEfl.cpp:159
> +        fireSpeechEvent(SpeechError);

Don't you need to set m_utterance = nullptr; as well ?

I expect this object will never be deleted, but I'm not sure about it now.

Thanks

But then m_isEngineStarted points to EE_INTERNAL_ERROR that is OK, which is a bit not intuitive. Maybe something like this
if !(m_isEngineStarted = espeak_Initialize(AUDIO_OUTPUT_PLAYBACK, 0, 0, 0) != EE_INTERNAL_ERROR)
     return false;

Now when initialization is wrong, m_isEngineStarted is false.
But early return is fine, I will change the code.

Looks better than previous patch. Please land after fixing trivial nits.
