Description

System and method for speech reception and detection Cross Reference to Related Applications The present application claims the benefit of U.S. provisional patent application No. 63/012,814 entitled "System and method for speech reception and detection" filed on month 4 and 20 of 2020, the entire disclosure of which is expressly incorporated herein by reference. The present application relates to U.S. provisional patent application No. 63/012,811, entitled "system and method for communicating information" filed on month 4 and 20 of 2020, the entire disclosure of which is expressly incorporated herein by reference. Technical Field The present disclosure relates generally to communication systems, and more particularly, to communication systems having microphones for voice reception and/or detection. Background Recreational vehicles such as motorcycles or off-road vehicles such as all-terrain vehicles (ATVs) and snowmobiles are widely used for recreational purposes. In riding, the user (e.g., driver/rider) may control some functions of the recreational vehicle through voice commands and/or may engage in telephone or radio communications. To this end, a user of the recreational vehicle (e.g., a driver/rider) may wear a wearable device with one or more microphones (e.g., headphones or a helmet with microphones) to capture the user's voice or speech. However, in addition to the user's voice, the microphone inevitably captures noise (e.g., engine noise, road noise, wind noise). Disclosure of Invention As described above, embodiments provided herein relate to speech capture for recreational vehicles. Exemplary embodiments include, but are not limited to, the following examples. In one aspect, a recreational vehicle is provided. The recreational vehicle includes a frame, front and rear ground engaging members supporting the frame, a powertrain drivingly coupled to one of the front and rear ground engaging members, a steering assembly coupled to the front ground engaging member for steering the recreational vehicle, a seat supported by the frame, and a communication system. The communication system has a microphone located between the seat and the steering assembly. In some embodiments, the recreational vehicle may further include a fuel tank supported by the frame and positioned between the seat and the steering assembly. The microphone may be mounted on top of the tank. In some embodiments, the recreational vehicle may further include an air box supported by the frame and positioned between the seat and the steering assembly. The microphone may be mounted on top of the air box. In some embodiments, the communication system may be configured to receive user speech of the recreational vehicle through the microphone. In some embodiments, the steering assembly may further include a front fairing and a user handle. In such embodiments, the microphone may be located behind the front fairing and below the user handle to reduce the amount of air in contact with the microphone. In some embodiments, the microphone may be mounted at an angle facing upward toward a user of the recreational vehicle to reduce the amount of exhaust noise and/or the amount of engine noise. In other aspects, a wearable device for voice detection is provided. The wearable device has a communication system including a processor, a microphone configured to generate audio data of user speech of the wearable device, an accelerometer configured to generate accelerometer data, capture vibrations of a head and/or neck of the user, and a memory including instructions that when executed by the processor cause the processor to detect the user speech using the accelerometer data. In some embodiments, generating the audio data may include generating audio data of the user speech in response to detection of the user speech. In some embodiments, detecting the user speech using the accelerometer data may include detecting the user speech by associating the audio data with the accelerometer data. In some embodiments, the microphone may be coupled to a wearable device near the user's mouth to receive speech from the user. In some embodiments, the accelerometer may be coupled to the wearable device at a location where the wearable device may be in contact with the user's head and/or neck to detect in real-time audio frequencies generated by the user's vocal cords. In some embodiments, the wearable device may be a helmet. In some embodiments, the accelerometer may be located on a chin strap of the wearable device. In some embodiments, the memory may also include instructions that, when executed by the processor, cause the processor to process the audio data using beamforming techniques to achieve spatial selectivity, filter the processed audio data to remove low frequency noise, and filter the accelerometer data to remove high frequency noise. In some embodiments, detecting the user speech using the accelerometer data may include correlating the filtered processed au
