Flock has ended its effort to use a network of microphones to detect signs of human distress. A small trial of the technology has concluded. Privacy concerns have not been resolved by the change.
The company announced it is pulling the plan after testing the system on a limited scale.
The microphones were intended to identify audio cues associated with distress. Flock has not provided further details on the trial results.
Privacy advocates have continued to raise issues about the potential for widespread audio surveillance even after the trial ended.
