I would do it like WWV. Have the time pulse generated artificially and its
audio synchronized, and have the voice mixed over the top. So long as the
voice message completes before the time mark, everything is fine. That
would allow the simple time pulse to be synchronous and the voice to be
asynchronous.

Hello Dana

The prototype system I built used an E1 digital telephony card with 30
lines. I think it cost about $12000/year to lease the associated 2
megabits per second data capacity but we didn't do that; we just
commandeered a few lines from our site's capacity.
I believe the live system needed several hundred lines to deal with
peak demand, usually at DST transitions.

The electro-mechanical-optical clock was made obsolete years ago and the

down is that the PSTN is digital and so delays are unpredictable leading to
possible errors in the time. According to a news item I saw the company that
runs the clock and supplies the audio wants to keep it going but the
national network supplier (Telstra) is determined to close it down because
of "network incompatibility". 

I made a talking clock with that format a few years ago. It is based on an
AVR processor that uses the mains frequency as a reference. The voice is
generated by an ancient speech synthesizer chip that sounds like Stephen
Hawking and the time is simultaneously displayed on a VFD. A PIR detector
switches off the outputs when there's no human around. It can be seen at

It wouldn't be hard to use the same platform to translate the time from a

Here in Australia we are suffering the loss of one of the significant

The talking clock, built in England, with sound tracks on rotating glass
disks, has been on the Australian telephone system for more than half a
century.
The system was timed by quartz oscillators, synchronised to the local
observatory time.
Now in spite of the trivial cost of maintaining the system it has been
removed by the money-hungry telco which took over the government run
telephone system. 
Now it occurs to me that the sound tracks occupy a very small digital space,

So is there a time nut who could design a voice output that we could all

Hi All,

I have the Tasmanian unit of the German made TTL based speaking clock
running in my garage. I've kept it going since it was decommissioned in the
mid 2000s. In true Time-Nuts fashion I have it synchronised to the GPS.

For extra fun, I broadcast it on FM 107.7 using a (legal) low power
transmitter. This means people in my neighbourhood can still hear the just
shut-down Australian speaking clock.

[time-nuts] Talking Clock

2019-10-01 Thread Mark Sims
It would be pretty easy to teach Lady Heather how to do it.  Heather already 
supports several different audible clock.   One issue would be constructing the 
message  from several snippets.  Currently Heather plays sound files 
asynchronously and if you start one file before the last one has completed they 
get mixed together.  Another issue to work out is the length of the combined 
message so that you know when to trigger playback.

Hi

Based on only dimly remembered conversations long long ago:

Getting all the “message fragments” so they sound natural and not choppy is
not quite as easy as it seems at first. It’s by not quite rocket science, but 
there
is more fiddling involved than one might think.

One “solution” is to use fewer fragments and record larger portions of the 
message.
Back in the day, storage limited your ability to record every message “full up”.


Typically one records 60 phrases - that is, rather than recording 
twenty, thirty, forty, and one, two, three and try to assemble them - 
you record all the numbers 00,01,02,03...


After all, your time is *free* to do the recording, and it makes the 
software to play it back easier (you don't have to figure out "is this 
less than 20 in which case play phrase[0] through phrase[19], and then 
play phrasetens[t/10] + phrase[t mod 10]






Assuming you record the “at the stroke the time will be” only once, the rest is
under 3 seconds of audio. At maybe 16 bits / 32K sps. (yes that’s overkill). 
this comes
up just under 200 K bytes. Recording the full time message for every minute of 
the
day would be less than 270 megabytes.



That would be a bit tedious..


There are, of course, myriad text to speech programs of varying quality 
available for just about every OS imaginable.  Although, in 10 minutes 
of casual browsing, I've not yet found one for Latin - a suitable voice 
intoning the time in Latin periodically would seem to be a good addition 
to any time cave.



Google translate does speak Latin, although I've not had my family 
classics scholar evaluate it.  To my ear, it seems to have a distinctly 
Italianate accent (a terminal vowel added to words), although it does 
say "Timeo Danaos et dona ferentes" and "Carthago delenda est" correctly.





That’s a pretty small flash drive ….

I designed the hardware and wrote the software for the now defunct
Australian speaking clock.
The prototype pieced together the audio from fragments and it did
indeed take quite a bit of effort to get this to sound clean.
Mismatches in sound levels at the boundaries caused 'pops', for
example. I spent about a week with my headphones on.

Re: [time-nuts] Talking Clock

2019-10-01 Thread vilgotch1
The electro-mechanical-optical clock was made obsolete years ago and the
voice is now generated electronically. I think the reason it's being closed
down is that the PSTN is digital and so delays are unpredictable leading to
possible errors in the time. According to a news item I saw the company that
runs the clock and supplies the audio wants to keep it going but the
national network supplier (Telstra) is determined to close it down because
of "network incompatibility". 

I made a talking clock with that format a few years ago. It is based on an
AVR processor that uses the mains frequency as a reference. The voice is
generated by an ancient speech synthesizer chip that sounds like Stephen
Hawking and the time is simultaneously displayed on a VFD. A PIR detector
switches off the outputs when there's no human around. It can be seen at
https://www.youtube.com/watch?v=lmg0YsHlB3g&t=3s

It wouldn't be hard to use the same platform to translate the time from a
GPS receiver into the spoken and visual word.

Here in Australia we are suffering the loss
of one of the significant developments in accurate time keeping and
dissemination.
The talking clock, built in England, with sound tracks on rotating glass
disks,
has been on the Australian telephone system for more than half a century.
The system was timed by quartz oscillators, synchronised to the local
observatory time.
Now in spite of the trivial cost of maintaining the system it has been
removed by 
the money-hungry telco which took over the government run telephone system. 
Now it occurs to me that the sound tracks occupy a very small digital space,
and 
with modern flash drives and a little logic the talking clock could be
driven by 
any time nut's disciplined time source.
So is there a time nut who could design a voice output that we could all
use?

?At the third stroke the time will be??

Hi

Based on only dimly remembered conversations long long ago: 

Getting all the “message fragments” so they sound natural and not choppy is 
not quite as easy as it seems at first. It’s by not quite rocket science, but 
there 
is more fiddling involved than one might think. 

One “solution” is to use fewer fragments and record larger portions of the 
message. 
Back in the day, storage limited your ability to record every message “full up”.

Assuming you record the “at the stroke the time will be” only once, the rest is 
under 3 seconds of audio. At maybe 16 bits / 32K sps. (yes that’s overkill). 
this comes 
up just under 200 K bytes. Recording the full time message for every minute of 
the
day would be less than 270 megabytes. 

That’s a pretty small flash drive ….

Bob

using Bash on my mac:

$ date +"The time is now, %H, %M, %S, coordinated universal time" | say 
-v Karen


I think that one could do a bit of scripting and have it have your 
preferred wording, and synchronized to the top of the second.


I leave it as an exercise for the reader to do it in French:
$ say -v Amelie "Le Temps Universel Coordonné"
