I've ordered Raspberry Pi 3 today and wanted to try the Jasper project on it. I'm new to RaspberryPi but have knowledge about linux environment and Python.
I've gone through the documentation page of Jasper project. I want to know that will I be able to try the Jasper project easily on Raspberry Pi 3, and will there be any major problem while setting up the whole thing. ?
TIA

Like you I have also put in an order today for some Raspberry Pi 3s. I will not know with absolute certainty if there are any issues until I have had a chance to test things on a Pi 3, but I doubt there will be any issues. The notes I made doing an install on a Raspberry Pi 2 should apply to the Raspberry Pi 3. For doing an install on the Raspberry Pi 2 I did the following:

---------------------------------------------------------------------

This is what worked for me:

Grabbed a copy of "Raspbian Jessie Lite" from:

https://www.raspberrypi.org/downloads/raspbian/

Installed it on a Micro-SD card (you want one that is at least 8GB in size) as per the instructions:

https://www.raspberrypi.org/documentation/installation/installing-images/README.md

Booted the image on a Raspberry Pi 2 model B, logged in, did

sudo su
raspi-config

in "raspi-config" I expanded the file system to take up the entire card, configured time zone, keyboard, etc.. Then I rebooted the Raspberry Pi 2 model B, did

sudo su
apt-get update
apt-get upgrade

Next I grabbed and ran the "jasper-installer.sh" script referred to here :

https://github.com/unixabg/raspi-helpers

This script does take several hours to run, but handles the downloading / installing of Jasper + all dependencies. Once the above is done you will need to create/tweak the ~/.jasper/profile.yml the details of which are described here:

http://jasperproject.github.io/documentation/configuration/

Then you can just run Jasper.

Hope the above helps.

Hey Colin, my Pi will still take some more days to get delivered to me. Did you received your Raspberry Pi3 ? Did you tried installing Jasper on it?

I received an e-mail this morning telling my my Pi 3s have (finally) been shipped, so I am still a few days away from being able to test Jasper on a Pi 3, sorry. I will post once I know more about Jasper on the Pi 3.

All the best.

What STT and TTS are you using? Do you have a config to share? Just looks like a configuration issue.

I'm now running mary-tts and using wit.ai, not running into that problem any more, thanks to Matt for helping me out. I'm still running into problems regarding IOError: [Errno Invalid sample rate] -9997. I have had a look at a few different posts and there seems to be a varying methods people have suggested to correct this. All i'm getting currently is...

So i’ve spent some time digging in forums and i’m struggling to pin down where i am going wrong. Some people have suggested that editing the ALSA file to make the usb sound card 0, i tried this and threw up a new error. Others have suggested it is to do with the chunk rate which i also tried changing, no success.

The search continues
