This is a simple detection application. It performs various kinds of detection on a local timeslot. It can only use the default tone tables. To test detection with new tone tables use tonedet.
Go to directory $(TiNG)/test.
You must have these firmware modules loaded:
Run detraw with the appropriate options (the program is
gen-LINUX_V6/detraw or
gen-WINNT_V6/detraw
depending on which operating system you are using).
Command line options are:
-a 1
| map tones to digits. This is only useful for detecting DTMF tones, in which case it shows the DTMF digit as digits rather than as codes | ||||||||
-C <alg>
| enable signal categorisation with specified algorithm | ||||||||
-c 1
| enable detection of call progress tones | ||||||||
-T <type>
| the type of tone detection to use. One of these
values:
| ||||||||
-g <duration>
| enable grunt detection with specified duration | ||||||||
-m <module>
| The Prosody module to use. This is the number of the module on the card. | ||||||||
-o <tonemode>
| enable tone detection with specified mode for
minimum tone duration (one of
"1", "40",
"64")
| ||||||||
-R <timeslot>
| the output timeslot to use as sidetone reference for isolated word recognition (see Test program timeslots). Note that this is an output timeslot - not an input. It should be a timeslot which is currently being used to generate the output which is to be regarded as sidetone by the recogniser. | ||||||||
-s <toneset>
| select tone set to use for tone detection | ||||||||
-t <timeslot>
| timeslot to use (see Test program timeslots). | ||||||||
-x <card>
| Use Prosody processor modules on this card, specified as described in Test programs: Specifying Prosody Processor modules |
For example,
gen-WINNT_V6/detraw -x x:1.2.3.4/mykey -t 64:0 -o 1 -a 1
would listen for DTMF digits using Prosody processor modules on the card with address 1.2.3.4 and key mykey.
When the program detects anything, it prints a description of what was detected. For example:
Digit: 42 (*) 0
means that it detected the DTMF digit *.
The source code for this program is provided (detraw.c).
This is one of the Prosody test programs .
