The most common device is a handheld, battery-operated device pressed against the skin under the mandible which produces vibrations to allow speech; [1] other variations include a device similar to the "talk box" electronic music device, which delivers the basis of the speech sound via a tube placed in the mouth.

Some automakers also said there is no need for electric-drive vehicles to play sounds while not in motion, "since it is not clear that it helps pedestrians to hear cars that are stopped in traffic or parked." In addition, the vehicle manufacturers requested the NHTSA to make the new sound system required by 2018 instead of 2014. [33] [35] [36]
Ringing is closely related to overshoot and undershoot, which is when the output takes on values higher than the maximum (respectively, lower than the minimum) input value: one can have one without the other, but in important cases, such as a low-pass filter, one first has overshoot, then the response bounces back below the steady-state level ...
Amazon announced new AI capabilities for its Alexa products last week, based on a model it’s calling AlexaLLM (LLM refers to the “large language model”). The technology will make Alexa ...
The torsional deflection of a simple cylinder cannot radiate efficiently acoustic noise, but with particular boundary conditions the stator can radiate acoustic noise under torque ripple excitation. [8] Structure-borne noise can also be generated by torque ripple when rotor shaft line vibrations propagate to the frame [9] and shaft line.
"These noise exposures can lead to a temporary shift in hearing accompanied by tinnitus, which usually resolves after 16 to 18 hours," Lewis says. "These exposures can cause temporary ...
Ringing noise from an electromechanical telephone Example of a short digital tune which could be used as a ringtone on a mobile phone. A ringtone is the sound made by a telephone to indicate an incoming telephone call. Originally referring to the sound of electromechanical striking of bells or gongs, the term refers to any sound by any device ...
Amazon Alexa, or, Alexa, [2] is a virtual assistant technology largely based on a Polish speech synthesizer named Ivona, bought by Amazon in 2013. [3] [4] It was first used in the Amazon Echo smart speaker and the Amazon Echo Dot, Echo Studio and Amazon Tap speakers developed by Amazon Lab126.
