Ros node handling calls to AWS TTS service
In one case, I run amazon_ros_speech
over ssh on a computer ("Victor Backpack") with no monitor connected.
Unfortunately, ubuntu 20.04 does not seem to play sound over ssh until after I log in. Once I log in, I can then run this script over ssh just fine.
This issue is not due to this repo, however I'd like to post a solution here
Hi,
I come from a research team which works on bugs in real-world applications.
I want to make a report about a few potential performance improvement in your project.
In file scripts/polly.py
, synthesize_speech
is called to generate audio files in each run. However, its input is a fixed string in call_polly(overload_str)
. This behavior increases execution time and brings unnecessary service cost. A caching mechanism could help such situation, e.g. save audio file on disk at first API call, and re-use that file later.
Perhaps someone might be able to confirm if these seem reasonable. Also, if you need any help, I'm happy to provide some code snippet for fixing.
If you are not offended by it, we may include your response as a percentage number (e.g. xx% of applications faces xx problem, and xx% of them confirms it) in our research paper.
Thanks.
