The SpeechMark R Package is now unsupported, and its use is deprecated. However, we invite anyone who is seriously interested in this Package to communicate with us and discuss their interest and needs.
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 R Package for Windows adds landmark support to the R software environment for statistical computing and graphics.
Features
The R Package:
- Analyzes speech files to detect and identify the location of acoustic landmarks
- Displays the location of acoustic landmarks.
- Landmark labels are superimposed on the audio signal waveform.
- Computes a Vowel Space Plot for detected vowel landmarks.
- In the Vowel Space Plot, SpeechMark plots the (F1, F2) positions of detected vowel landmarks.
- In addition, as a visual guide, SpeechMark also draws a polygon (dashed blue line) showing the approximate range of the adult vowel space. That is, the polygon shows accepted values of the adult vowel space, (not boundaries derived from the vowels being plotted).
- Calculates the number of syllables, the number of utterances and the number of landmarks in syllables and utterances.
- Saves and Loads landmarks data to disk.
System Requirements
- Windows XP or Windows 7
