My company would like to distribute devices containing preinstalled Google Text-to-Speech (TTS) engine, together with some downloaded offline voice data.
Can we do this without the need to acquire any additional licenses/permissions?
My findings in this matter are insufficient, but I'm going to present them here anyway, to avoid confusion:
- Android TTS framework is a part of Android Open Source Project, licensed under the terms of Apache 2.0 license, making it perfect for free distribution
- The framework allows multiple TTS engines, including Google TTS, which comes as a part of the operating system installed by devices' OEM.
- As far, as I understand, the usage of Google TTS is governed by Google Terms of Service, which does not say much about preinstalling parts of otherwise available online Google software or its data On my device
- As a user, I can go to Settings and download any of the available Google languages for offline use.
