I'm sorry, I thought that the 'copy from about:version' tag in the bug template would be auto-filled.  The Chrome version I'm using is:

Able to reproduce this issue on Windows-7, 10 and Ubuntu 14.04 using chrome latest stable M55-55.0.2883.87 by following steps mentioned in the original comment. Observed the Speech Synthesis stops while reading the paragraph 2.

Good build:55.0.2875.0
Bad build: 55.0.2877.0

Using the per-revision bisect providing the bisect results,

You are probably looking for a change made after 421957 (known good), but no later than 421958 (first known bad).


From the CL above, assigning the issue to the concern owner

Hello, sorry to bother, but has there been any progress on this bug?

Comment 6 by, May 13 2017

this issue is crucial, and should not be abandoned. 

we are talking about a bug that renders a big chunk of the users (people with disabilities) helpless. 

this is not fair for the exceptional website who go through the effort to make their website accessible.

i'm getting horrible reviews on my free extension [0] because of this bug.

Wesam, I've found that you can work around this bug by chunking text or pause/play speech at regular intervals. Hope that helps.

I realize this feature may not get as many votes or be as useful to every person who uses the Internet, but the same can be said about wheelchair ramps.  The customers we hear from who need this feature are school children.  Please think of the children.

After upgrading to Chrome 61 (Version 61.0.3163.100 (Official Build) (64-bit)) this bug appears to be gone - at least the demo now passes.  If someone else can confirm then I presume this issue can be marked as resolved, but it would also be nice to know if it was version 61 or another release that fixed it so the notes on can be updated to reflect the affected versions.

Thank you,

Confirmed working in Chrome 61 (Version 61.0.3163.100 (Official Build) (64-bit)) on Windows 10.

With Chrome version 63 (Linux) the problem is still present. There is a very simple fix. periodical call of speechsynthesis.pause();speechsynthesis.resume(); solve the problem.

Comment 16 by, Jan 30 2018

Bug is still present in Chrome 64 on Ubuntu.
