Getting SNIMissingWarning and InsecurePlatformWarning in python 2.7.3

[chan71]

In which file did you encounter the issue?

transcribe_streaming.py

Did you change the file? If so, how?

Yes, see attached file.
trans_streaming_1.txt

Describe the issue

We executed a modified version of transcribe_straming.py on NAO robot OS which has python 2.7.3 as updating it to 2.7.9 or above is not possible due to the dependency of some of the NAO functionality on the python 2.7.3. We are getting the following warning messages when we run the modified script. In addition, we have tested the script with various buffer sizes and sleep times in reading data from arecord command to send to google cloud speech API just to find that transcripts are taking more time than it should when buffer size = 3200 and sleep = 0.1 s. For any other combination, it gives one error or the other.

I have given details of our observations in this comment of the ticket #738 .

/var/persistent/home/nao/googlespeech/env/lib/python2.7/site-packages/requests/packages/urllib3/util/ssl_.py:334: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this.

 SNIMissingWarning
/var/persistent/home/nao/googlespeech/env/lib/python2.7/site-packages/requests/packages/urllib3/util/ssl_.py:132: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. You can upgrade to a newer version of Python to solve this. For more information, see https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings
 InsecurePlatformWarning

As per the https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings and http://stackoverflow.com/questions/29134512/insecureplatformwarning-a-true-sslcontext-object-is-not-available-this-prevent we tried out fix the above warning but none was successful in NAO robot OS.

My questions are,

1. Is there any issues that you have noticed in python 2.7.3 similar to above and is there a way other than updating python version to resolve these?
2. Can this error contribute to a slowness in getting the transcripts from API?

Use pyOpenSSL

2. Can this error contribute to a slowness in getting the transcripts from API?

Unlikely
