A voice alert system 10 for use on bicycles and similar human-powered vehicles. When triggered by the user, it generates one or more safety alerts in the form of pre-established voice messages. It consists of a switch assembly connected to a random-access voice playback module, which in turn drives an amplifier and forward-facing speaker. These components are supported by a main housing and a speaker housing, which in turn are attached to the the host bicycle by means of a clamp assembly. The switch assembly includes at least one switch for producing a triggering signal. On receipt of the triggering signal, the voice playback module produces an electrical representation of a pre-established voice alert, which is amplified by the amplifier and projected by the speaker. Optionally, one or more additional switches are provided to trigger one or more additional voice alerts. The content of the voice alerts will typically be safety-related, such as "passing on your left", "passing on your right", etc., and will typically have humorous or entertaining accents or dialects to encourage use. One or more alerts may be pre-established at the factory; optionally, the voice playback module can be provided with a recording capability to allow the user to record his or her own alerts.
