Harebrain Inc The Whisper Phone enables children to hear phonemes ten times more clearly as they learn to read, spell, or process language aloud. By channeling voices directly to their ears, children hear what they are reading, even at a whisper, keeping the classroom quieter and helping each child concentrate on his or her work. Besides supporting independent oral reading, the Whisper Phone is a great way to help kids. Accelerate development in speech training. Learn a new language (ELL students). Proofread written work for completion and correctness. Sound it out during vocabulary and spelling practise. Discover a singing voice without disrupting others. Reversible for either ear. No batteries or wires.
