TruTone is a "light weight and small size" (the device weights approximately 128 grams) electrolarynx that features a on/off button with pressure sensitivity that allows the user to control the pitch of the produced sound with only one thumb on the device. It also features a thumb wheel to control the volume. The manufacturer advertises that the device has the widest tonal range available in comparison to competing devices. It is equipped with one 9 V battery but it is not clear whether the included battery is rechargeable. The manufacturer offers 5 years warranty within the United States. The device costs 600 USD.
The TruTone series of devices is directed towards laryngectomees that have lost their ability to produce speech. The usage of an electrolarynx allows them to communicate in a quick and natural manner without resorting to other means such as pen and paper.
