Whisper Phone is an educational tool designed to support reading development, pronunciation, and phonemic awareness. Using a simple voice amplification tube, Whisper Phone provides immediate auditory feedback, allowing learners to clearly hear their own voice and focus on their speech. Originally developed from a classroom need and refined through close collaboration with educators, Whisper Phone helps improve reading fluency, sound awareness, and attention while reducing background noise distractions. Used in classrooms, speech therapy settings, and at home, it is especially effective for emerging readers, English language learners, and students who benefit from auditory feedback.
