Speech Physiology and Acoustics Lab

Description: The Speech Physiology and Acoustics Lab provides access to observation, measurement, and manipulation of speech production and perception proocesses. Measurement capabilities include electroencephalography (EEG), evoked potentials (EPs), electromyography (EMG), kinematics of the lip and jaw movement, respiration, and acoustic features of normal and disordered communication. The lab is open to faculty and students for a wide variety of teaching, research, and clinical assessment/intervention projects.

Instrumentation: The lab is centered on a Mac G5 computer and an external instruNet Data Aquisition input-output converter and internal PCI bus controller card. Instrumentation is available for a variety of neurophysiological measurements including electroencephalography (EEG), evoked potentials (EPs), and electromyography (EMG). Analysis of vocal fold behavior (EGG) is accomoplished via an EG2-PC Electroglottograph with lip and jaw movement via a custom build head mount strain-gauge system. A Respitrace is usesd to assess respiratory behaviors. High quality analog and digital audio recording is available for input and analysis via a Sure studio microphone (model SM7B), six-channel audio mixer, and a Delta 66 sound card.

Software: The GW Instruments SupereScope II and SoundScope software provide for data aquistion, display, and analysis . SuperScope II is a laboratory instrumentation design environment that can be used to build virtually any software laboratory instrument. It can digitize, analyze, display, calculate, graph and database waveform data. SoundScope is a speech and sound analysis software program that can record sound, perform extensive acoustic analysis, extract key values, and compute statistics on virtually any audio data set. Sound display capabilities are extensive and flexible including basic waveforms, spectrographics, two and three dimensional spectrums, Fo, intensity, etc.

Multimedia Lab

Description: The Multimedia lab is equipped to handle a wide variety of audio and video projects such as A/V media transfer, editing, movie development, audio tape development, A/V compression, animation development, and CD/DVD burning. The lab is availble to faculty and students for teaching, research, and clinical projects. A lab manual provides the inexperienced user easy to follow directions for carrying out typical multimedia projects.

Instrumentation: The Multimedia lab is based on a PowerMac G5 computer with both analog and digital interfaces. Hardware includes two JVC audio-video take recorders and playback decks, one VHS/S-VHS format capable and one that handles VHS, S-VHS, and Mini DV format tape allowing for complete anolog-to-digital and digital-to-anolog media conversion and dubbing. A Sony VHS U-Matic tape recorder and playback unit is also available for older 3/4" tape formats. The system has two monitors for ease of video editing and playback, a NEC 17" LCD monitor and a Monivision 27" monitor. A three-way Fostex speaker system produces high quality audio monitoring. The system also includes an HP 5470c Scanjet Scanner, two firewire external hard drives for data storage (200 GB and 160 GB), and a LaCie multi format DVD/CD burner.

Software: A variety of software options are available for high quality audio-video media editing and development. The primary software include iMovie, iDVD, and Final Cut Pro for audio-video movie editing and development. DVD studio pro. Cleaner, and Roxio Toast are available for media compression and DVD/CD development. Photoshop is available for image editing. Both Macromedia Flash and Macromedia Director are are used for developing high quality animation and multimedia materials.
