Please add response data (introduced in 2023.7) to tts.cloud_say, which would contain url generated by this call. Also please add new optional boolean parameter to this service, which would toggle between local and cloud url returned in response data.
Having cloud (instead of local) media url would allow to use it in Echo Dot via custom Alexa Media Player integration, because alexa api supports playing cloud mp3, but not local one. It doesn’t matter if the cloud url would be valid only for couple of minutes. It’s TTS, you’d hardly want it to read something longer than 2 minutes…
