tts: unbearable stop at the end of every line

[JoeyRxy]

there's an obvious stop on the end of each every line.

I've tried Google and samsung tts services, they all came with the same problem.

here's an example I've recorded:

and here's part of the settings might be related.

this is irrelevant to the file format because I've tried the epub and pb2.

is this normal?
