As an alternative to using the different individual audio preprocessing options, you can use the audioAnalysis
task to combine a number of the key audio preprocessing tasks that are supported by the audiopreproc
module in a single task. The audioAnalysis
task includes the following functions:
speechSilClassification
task. DTMF and dial tones can optionally be included in the output, by using the DoToneClass
parameter.SNRCalculation
task.ClippingDetection
task.AudioAnalysis
task.To run audio analysis
Send an AddTask
action to IDOL Speech Server, and set the following parameters:
File |
The audio file to process. |
Out | The XML file to write the audio analysis summary results to. |
For example:
http://localhost:15000/action=AddTask&Type=AudioAnalysis&File=C:\data\Sample.wav&Out=SampleAnalysis.xml
This action performs audio analysis on the Sample.wav
file and writes the results to the SampleAnalysis.xml
file.
The AudioAnalysis
task also produces an additional audio classification .ctm
file. By default, this file has the same name as the task token. You can use the GetResults
action with the label
parameter set to class
to retrieve this file.
For more information, see the IDOL Speech Server Reference.
