Headless Raspberry Pi, Tell me my IP - Text-to-speech working for you

recantha

Just published a new blog post bringing together everything I've found about determining the Pi's IP at boot time and reporting it vocally over the 3.5" jack using the Festival text-to-speech package..

I've got it so that the Pi vocally tells me it's IP address. During start-up, however, the IP address over wifi takes a while to be acquired, so my script take this into account.

    Works okay through the 3.5mm jack - I'm almost scared to plug the HDMI in!

    Oh dear, Festival seems to have problems on Raspbian.  With audio routed to HDMI it just makes a clicking sound on the TTS "hello" test, and with audio routed to the analogue port it hangs the audio device forever, and nothing short of a reboot will restore it.

     

    I wish the Foundation weren't using OpenMAX but had ported ALSA instead.  ALSA is after all the standard audio system for Linux.  Troubles ahead.

  • That's pretty cool, Michael.

     

    I like Festival, I've been using it daily for as long as I can remember, in two different roles:  a text-to-speech plugin for an IRC client I hacked way back (via speechd and then into Festival), and in a simple ISP death monitor ("Blah blah ISP is down!") which targets my various providers.

     

    The machines all have their audio outputs fed into a 16-channel analogue mixer which is then routed from the computer room via an S/PDIF coax driver into the lounge hifi a floor down and some rooms away, and from there the whole house can be fed as needed.  It integrates the TTS messaging nicely with my various other domestic audio sources.

     

    Networked TTS is actually a function that matches Pi's properties very nicely, because neither the audio nor the networking requirements are onerous, and the Pi can just sit there forever handling these functions at a very low duty cycle without consuming too much power.

     

    I'm glad you blogged this, as it's so perfectly suited to Pi.  I think I'll dedicate a Model B to networked TTS functions myself once they're ex-stock.  Good suggestion! image

  • Great idea!  This would definitely be useful to me when a display or serial cable aren't available.
