As you know, with addSpeech () in android TTS, you can associate specific text with a sound file. The tts engine then plays the file instead of synthesizing the sound of the text.
Using Google TTS (not Samsung TTS), from Marshmallow (api 23) above, addSpeech and speak can not play the file in external storage. Before Zephyr, everything was in order.
For those using android tts and addSpeech, check out the codes below and help me find the problem.
- The codes were from http://www.java2s.com/Code/Android/Media/MediaPlayerandTexttoSpeech.htm , and I changed them to prove my point.
- The permission WRITE_EXTERNAL_STORAGE is specified in the manifest, and TargetSDK is set to 22 to avoid problems with permission to run Raven.
- You need to put boy.mp3 in the DOWNLOADS folder on your device. ( https://dl.dropboxusercontent.com/u/61874191/boy.mp3 )
- The code works fine in 22 devices and Samsung TTS. It does not work with 23 above and with Google TTS.
If I save the file in internal storage (with MODE_WORLD_READABLE), it works fine even with Google TTS. But MODE_WORLD_READABLE is now deprecated, so I would prefer external storage.
Thank you for your attention and had a good time.
