The SpeechMark family of products detects and measures acoustic landmarks —acoustic events that correlate with changes in speech articulation. Landmarks are useful for investigating non-lexical attributes of speech, such as differences in production of the same speech material by the same speaker under different conditions.
The SpeechMark Command Line Utility, Windows Edition is a version of the SpeechMark technology that is callable from a Windows command window. The utility is a command line program named spmark.exe, which processes a wave file containing recorded speech, detects acoustic landmarks in the recorded speech, and outputs a text-format “landmark file” with information about the detected landmarks.
Features
The text output of the SpeechMark Command Line Utility can be imported into other programs. This utility is well-suited for batch processing, as no user interaction is required when the program is running. The Utility is designed to be easily integrated by the end user into most third-party speech processing systems.
The SpeechMark Command Line Utility is primarily suited to the following uses:
- Analyzes a speech file in order to detect and identify the location of acoustic landmarks (See How are Acoustic Landmarks Detected?)
- All SpeechMark products generate a landmark file (“.lm”), which is a text file that contains one line of information for each generated landmark. That line contains a timestamp, the label of the landmark, and a numerical “strength” value; An example of the first few lines from a .lm file is shown below.
Examples
The following figure shows two invocations of spmark.exe:
- The first invocation shows how the “/?” option is used to print help describing the program’s command line syntax;
- The second invocation highlights the specification of one input filename as a required argument on the command line. The specified file is the .WAV file that contains the speech in which landmarks are to be found.
System Requirements
- Windows XP or Windows 7;
- The MATLAB Compiler Runtime (MCR) object. This third-party software is installed automatically if it is not found on the user’s system by the SpeechMark installation process.
