PIPS (Speaking Clock)

A pips and speaking clock emulator for Python using espeak and pysine on Linux

Tip: Use an NTP server to sync your computer with the correct time

How to sync a watch or clock:

To sync an analogue time device, hold the device from ticking when the second hand reaches 12 or 0. Set the mintue hand accordingly as spoken on the :30 second time signal of the speaking clock. Wait for the :45 signal and on the long stroke set the time device to start ticking again.

Launch:

python3 -m speakingpips --type=clock
  • :00 On the first second a long stroke signals to start of the minute
  • :15 The current minute will be announced
  • :30 The next minute will be announced
  • :45 The time signal will begin

Available pip signatures for pips.play():

  • uk, gts (The original pip signature)
  • New Zealand (nz)
  • Ireland (ire)
  • United States (usa)
  • Japan (jap)
  • Australia (aus)
  • Italy (ita)
  • Germany (ger)
  • India (ind)
  • China (chi)
  • Hong Kong (hk)
  • Isreal (isr)
  • Romania (rom)
  • Slovakia (slo)

Install

$ mkdir -p ~/git && cd ~/git
$ git clone https://github.com/duracell80/pips.git
$ cd pips && chmod +x *.sh

$ ./install-deb.sh
$ python3 -m pip install .

ALSA Buffer Underrun

Sometimes the audio can be choppy and messages from ALSA complain of buffer issues, likely from how short the pips are.

$ sudo nano /etc/pulse/daemon.conf

uncomment and change these lines to:
default-fragments = 5
default-fragment-size-msec = 8

Usage - On command line

python3 -m speakingpips --type=pips --lang=jap
python3 -m speakingpips --type=clock

python3 -m speakingpips --type=clock --loops=10 --lang=en-sc --message="On the last stroke the time will be"

Usage - In scripts

import time
import speakingpips as pips

pips.play("gts") # Greenwhich Time Signal
pips.play("jap") # Japan

# Speaking Clock ...
Params: 
- language (espeak --help), 
- message prepend,  
- number of loops (0 infinite), 
- False = use python module, True = use command line call

pips.speak_clock("en", "On the long stroke the time will be", 100, False)

ToDo:

  • Allow script to run seconds ahead of actual time to account for when broadcasting digitally
  • Look at ways of cleaning up choppy audio (buffer underun)
