     SpeechMark™ products are commercial software tools for detecting and identifying acoustic landmarks in digital speech waveforms. These tools are designed for speech scientists, linguists, signal processing engineers, and other researchers, to help them detect changes in the way speech sounds as a result of variations in speakers’ physical health, mental and emotional state, and stage of development.

     Acoustic landmarks are locations within a speech signal where important and easily perceptible speech properties are rapidly changing. These sites of rapid acoustic change correspond to important articulatory events, which in turn reflect underlying cognitive, mental, emotional, and developmental states of the speaker.

     Acoustic landmark analysis was pioneered at MIT by the Speech Communication group, and further developed by Speech Technology & Applied Research Corporation (STAR). Now, supported by NIH’s “Lab to Marketplace” program, STAR is proud to introduce their SpeechMark line of products to the world…
