Google AI TTS disabled in voice pipeline

Any idea how to enable “Google AI TTS” in voice pipeline (can’t be selected in the dropdown)? It seems it can be enabled for English, but not for Czech or Slovak despite tts.speak working flawlessly for these languages.
Thanks, jose

              _attr_supported_options = [ATTR_VOICE]
              # See https://ai.google.dev/gemini-api/docs/speech-generation#languages
              _attr_supported_languages = [
                  "ar-EG",
                  "bn-BD",
                  "de-DE",
                  "en-IN",
                  "en-US",
                  "es-US",
                  "fr-FR",
                  "hi-IN",
                  "id-ID",
                  "it-IT",

Open an issue requesting new languages.
Or create your own custom_component and make the necessary changes.
But in general, this TTS is very slow. Therefore, the idea does not make sense.

Thank you. You’re right, it’s currently not the best fit for interactive chats.
