Not selling this right now. Sorry.
Speak 'n Hear-A Pocket Portable Audio Studio used for; Speech Therapy, Voice Training, Speech Analysis, Foreign Language Training, Stage and Karaoke Performances, a Music System, a Voice Amplifier, a Megaphone, an Intercom, a Hearing Assister, a Learning Center, a Cell Phone Attachment, or a Sound-Level Meter. Developed by Amantha Cole & Arthur Cole
Speak 'n Hear A is a 5-ounce pocket audio unit that uses headsets (microphone plus headphone) to feed back the user's voice to the user's ears. With feedback the user can recognize problems in speech, singing, or language development and correct them quickly in real time. This is possible whether the user is a novice or talented speaker, actor, singer, or has a speech handicap (Speak 'n Hear does not have Delayed Auditory Feedback used in stutter therapy). When vocal or musical inputs are added the user can improve enunciation and placement of pitch and tempo. The portable 16 ounce Speak n Hear B has the same circuitry as A but adds stereo loudspeakers and a shoulder strap. Either unit, with the 3-ounce Mini Audio Studio attached, supports eight headsets or 18 inputs/outputs that can be interfaced with many audio devices.
Although Speak n Hear was first made to exploit voice feedback as a training or therapeutic tool, continuing refinements led to the expanded uses outlined here.
A Speech Therapy tool for Adults or Children with Speech or Hearing Impediments such as autism, stuttering, and mental or hearing handicaps.
Voice Training/Monitoring for Speakers, Actors, Vocalists, and Karaoke singers.
Voice Training to learn or improve speaking a Foreign Language.
A substitute for Public Address (PA) Microphones for one or more performers, who can monitor either their isolated voices or all inputs to the PA system.
An Interface to a computer to run Voice Analysis programs while simultaneously hearing the vocal inputs to the computer.
A Portable Audio Studio with 18 inputs/outputs.
An eight-place Learning Center that accepts a variety of audio/visual inputs/outputs.
A two to eight-place Intercom for noisy environments (Aircraft, Helicopters).
A pocket Home Amplifier to power efficient loudspeakers to 100 dB (decibel) levels.
A personal portable Voice Amplifier to provide a 25 dB boost for voice-limited users.
A portable Megaphone for announcements to small groups.
A 20 dB sound-level booster to improve hearing faint speech or sounds.
A Cell or Mobile Phone attachment that lets up to eight persons join in two-way calls.
A Diagnostic Tool to check or adjust microphones, earphones, players/recorders, audio/visual devices, and computers.
A dB Meter for 50 to 115 dB (with digital voltmeter and calibrated microphone).
Speak n Hear Units. Unit A is 1X2X4 inches and Unit B, with stereo loudspeakers, is 1X6X6 inches. Both use a 9 volt battery with a 100 hour lifetime. Adapters supply power from AC line or DC auto sources. Speak n Hear has the unusual capability that it mixes High-Level signals (at amplifier outputs) in addition to the usual mixing of Low-Level signals (at amplifier inputs). Both High-Level and Low-Level signals can be patched from or to external systems. Both units have the following controls and connectors.
An input jack for an external Power Adapter.
A Power On/Off switch.
A Volume (Gain) Control.
A switch to set Relative Amplifier Gains of X1 or X10.
Two Mic jacks used for Microphones or for Low-Level inputs or outputs.
A switch to select Low Z or High Z input loads for Mic 2 for different mic types.
Two Stereo Headphone Jacks also used for High-Level inputs and outputs.
An External Patch In jack to patch High-Level Stereo or Mono from an external amplifier to the Speak n Hear headphones when the Mode Switch is on Ext Patch.
A Mode Switch to select whether audio to the headphones comes from the Internal Speak n Hear Amplifier or from the External System.
Speak n Hear B has an additional control.
A Loudspeaker Mode Switch to turn off the speakers or connect them either to the Monaural Internal Speak n Hear Amplifier or to a Stereo or Mono External System.
Mini Audio Studio attachment. The 3 ounce Mini Audio Studio attachment has eight Monaural Low-Level input/output jacks, that connect to the two Mic jacks of Speak n Hear, and eight Stereo High-Level input/output jacks that connect to one Headphone jack of Speak n Hear. A switch on the Mini-Studio adds 10 ohm isolation resistors between the Mini Studio high-level jacks and the Speak n Hear headphone jack (mixing of High-Level signals is enabled using isolation resistors on each high-level input). Low-Level Jacks are used for microphones; or to input or output low-level signals from or to external devices. High-Level Jacks are used for headphones or loudspeakers or to input or output high-level signals from or to external devices. Special cables are used, either with self-contained isolation resistors/capacitors or with small adapters, to patch Speak n Hear or the Mini-Studio to external audio systems.
