Please make sure you enable AwesomeTTS Plus: Get your API key here: https://cloud-language-tools-prod.anki.study/request_patreon_key , and paste it into AwesomeTTS Options -> Advanced -> AwesomeTTS Plus. Then click verify.
Once you do that, you'll have access to Azure, Google, Naver, Amazon and Watson voices without having to enter any other API keys !
This latest release adds the ability to set preferred users in Forvo: go to Awesome TTS Options -> Services, then enter a comma separate users of users whose pronunciation you prefer. Then when generating voices, you have the option to look for audio only from those users. This was a feature request by a patreon fan.
Also, this release adds back the Welsh voice in Amazon, and adds AwesomeTTS Plus support for Watson.
