I’m trying to get the Google TTS API to pronounce foreign words properly, but can’t figure it out. Aside from their demo:

<speak>The french word for cat is <lang xml:lang="fr-FR">chat</lang></speak>

Almost anything else I try is ignored, for example (cloud API demo URL if you have an account):

<speak>I visited <lang xml:lang="lt-LT">Rūdiškės</lang>, which should be pronounced as <voice language="lt-LT" gender="male">Rūdiškės</voice></speak>

If you can’t visit that, the first pronunciation is like “Ru-di-skis”, and the 2nd one “Ru-dish-kes”. And FWIW, the issue with the above “working” SSML is that it changes the voice model, so is quite jarring.

According to their docs, that’s all I should need to to, but I can’t figure out why it isn’t working.
