Broadlink RM2 Pro & Google Voice and later Echo Dot

[gsuemnic]

Newbie here.
 I just purchased a Broadlink RM2 Pro and I’ve seen several  posts stating,   that along with tasker, I could use Google voice to issue commands  to my TV and/or cable box.
I’ve watched a couple you tube videos but can’t seem to find a place with clear step by step directions.
For example a simple ‘cable box on’ command to start.I just need to find a basic template.

Sure seems the sky’s the limit with tasker, etc.  I’m surprised there isn’t a site to purchase the necessary tasker actions/tasks.

Later I plan on buying an Echo but would like to start with Google voice.

Thanks in advance.
