ZVOX Portable Speaker Provides Clear Dialog for Video Conferencing

Palm-sized AV70 uses AccuVoice algorithm to clarify voices on calls.

ZVOX has added the compact portable AV70 Bluetooth AccuVoice speaker to its line of dialog-enhancement products. Powered by a rechargeable lithium battery, the AV70 is a “must-have accessory” for people who are always on the go, enjoy streaming entertainment, or use video conferencing for personal and business use. It’s designed for conference calls on Zoom, Microsoft Teams, Facetime, or other video-calling systems. It is also good for use while watching videos on a tablet or laptop computer — producing full-range music and soundtracks while clarifying dialog.

“The use of video conferencing exploded during the first year of the Covid crisis. But many people had trouble understanding what was being said,” comments ZVOX founder Tom Hannaher. “On important business conference meetings, and on millions of family video calls, folks kept asking, ‘What did she say?’ Our little AccuVoice conference speaker fixes that.”

Measuring 4 inches wide by 2.2 inches high and with a hands-free microphone, the AV70 can run for 24 hours on a single charge. Notably, it features ZVOX’s proprietary AccuVoice dialog-clarifying technology, with advanced hearing aid technology to make voices crisp and easy to understand, even at low volumes.

The AV70 connects wirelessly to any phone, tablet, or computer using Bluetooth (a wired connection is also available) and lets listeners hear every word on every call.

Using a version of the AccuVoice technology that ZVOX utilizes in its hearing aids and home entertainment AV speakers, the AV70 both boosts audio frequencies in the range of speech and suppresses background noise. AccuVoice technology “lifts” dialog out of phone calls or TV programming, so voices can be heard more clearly and succinctly. The net result is that words stand out and are easier to understand.

The speaker is Bluetooth-capable and can handle a wired connection as well. Simple topside buttons allow for the activation/deactivation of AccuVoice, volume, pause/restart video – and even phone answer and hang-up.

The new ZVOX AV70 is priced at $99.99 and is available now on
