Kri’at Shema in a Whisper
As a speech therapist, I was wondering whether Kri’at Shema can be done in a whisper. In a whisper, the “z” sound is produced as an “s” and the “v” sound is produced as a “f” (and all voiced sounds become devoiced). Scientifically, this is because the vocal chords do not vibrate when whispering. Doesn’t one need vocalize to truly produce a “zayin”, “vav”, or any voiced sound, when saying Shema?
