I tried reproducing the issue from develop with x30 speech rate and it continued playing for more than an hour.

• Are you able to reproduce the problem in the Test App from develop (3.0)? We won't fix the issue in 2.4.0.
• Does it happen with any book or one particular book? If yes, can you send us the book?
• Does it always stop on the same utterance/phrase in your test book?

Hi Mickael, Its working on 3.0.0-beta(develop branch). Can we add the fix to 2.4.0 version as hot fix. Thanks

As the 3.0.0 version is nearing release, we don't do hot fixes on 2.4 unless critical issues preventing the build. I suggest you migrate to 3.0.0-beta already, which is pretty stable and already used in production by a few apps.
