For the fun of it, I thought I'd give a 7-Day forecast to my RadioDJ installation for playback in the morning--and maybe at other points throughout the day. After a bit of tinkering, I've come up with a solution that'll pull my local forecast and speak it into a waveform file, which I have imported into RDJ as a "variable duration"--see my previous post for a quick explanation of that RDJ file-type.
In a folder under RDJ, I put the executable and dlls from GNUWin32's wget port, and a little .vbs script (for TTS conversion) from the Jampal mp3 Library.
Next, I put together a batch file and a powershell script that would process the NWS Forecast information and create the waveform:
nws.bat: @echo off CD C:\RadioDJ\Media\NWS :: get the forecast wget ftp://tgftp.nws.noaa.gov/data/forecasts/zone/ky/kyz037.txt :: remove header, end characters for /f "skip=14 delims=$$" %%a in (kyz037.txt) do ( echo %%a >>forecast.tmp1 ) :: put text into one line (for TTS readability) setlocal DisableDelayedExpansion (for /F "usebackq delims=" %%a in (forecast.tmp1) do ( set /P "=%%a" < NUL )) > forecast.tmp :: filter NWS abbreviations (and certain words) and replace with TTS friendly pronunciation values powershell -command .\nws-filter.ps1 :: read the forecast into a WAV (NOTE: uses the 'default' computer voice) cscript ptts.vbs -w forecast.wav -s 48000 -c 1 -r 2 < forecast.txt :: cleanup the temp files del .tmp del *.txt nws-filter.ps1: $lookupTable = @{ '50s' = 'FIFTIES' '60s' = 'SIXTIES' '70s' = 'SEVENTIES' '80s' = 'EIGHTIES' '90s' = 'NINETIES' '100s' = 'ONE-HUNDREDS' 'mph' = 'MILES-PER-HOUR' 'winds' = 'WINNEDS' } $original_file = 'forecast.tmp' $destination_file = 'forecast.txt' Get-Content -Path $original_file | ForEach-Object { $line = $_ $lookupTable.GetEnumerator() | ForEach-Object { if ($line -match $.Key) { $line = $line -replace $.Key, $_.Value } } $line } | Set-Content -Path $destination_file
...personally, I love the change I have to make to "winds" ;-)
The powershell script can be edited later, for when I inevitably run across other words that aren't pronounced right. Other filtering may be mandatory with other voices/engines... For example, the default voice I'm using--Microsoft Speech Server ZiraPro--will skip over ellipsis, whereas Microsoft Anna reads them as dot-dot-dot. Your mileage may vary.
...I guess the next thing I have to figure out is how to handle "immediate" bulletins... ;-)

hello, i'm going to try this setup, however i have to assume it will be plain TTS, is there any command line tool to place a background music under this? like something that can take the generated audio and mix it with a piece of bed music?
Been a while since I tinkered with this stuff, so this isn't going to be the greatest answer...
To go a command line route, I'd see about trying to play with ffmpeg or maybe mencoder. (When I messed with audio in command line I usually had best luck with ffmpeg)
...if you try ffmpeg, I think I found an answer:

I remember that when I was playing my files back through radiodj I had created a special bed that was several minutes long--since the length of my WX file varied day to day, and I created an event or playlist or something that cued the bed, played the WX, and faded the bed on completion of WX playback. I can't remember how I did it, but I know there's an answer in the RDJ forums somewhere, if you're using that.
