RFP Title
Real-time Detection of Human Voice in Noisy Environments
RFP Description

NineSigma, representing a multibillion-dollar manufacturer, seeks a technology for real-time detection of human voice in noisy environments.



The major manufacturer, a client of NineSigma, is engaged in the development of unmanned aerial vehicles (UAVs). Enormous research effort has been made to extract spoken human voice in outdoor environments where UAVs are in use, in order to leverage the voice data for some applications. However, mechanical noise generated from propellers and other noises from surrounding environments make it more challenging.

technology, the real-time detection of the voice is found to be particularly difficult to achieve. In recent years, however, the development of a technology to extract and recognize human voice for various applications, such as mobile devices, has been widely active. Therefore, the client has issued this open request to further accelerate the development of such technology by seeking proposals from potential development partners.


Key Success Criteria

Overview of noisy environment and voice to be detected

  • Noisy environment
    • Type of noise: Mechanical noise, sound of rain and wind, etc.
    • Sound pressure: Approximately 100 dB
  • Voice
    • Frequency: Approximately 100 – 1000 Hz
    • Sound pressure: Much lower than the noise; approximately 80 dB


Requirements of the technology to be ultimately developed

A technology or system capable to figure out the presence of human voice in the abovementioned noisy environments; the requirements are as follows.

  • Usage environment: Basically outdoor
  • Size: Approximately 10 × 10 × 10 cm at maximum
  • Weight: Should be eventually possible to be a few hundred grams or less
  • Processing speed: In real time
  • Accuracy: Able to determine the presence of human voice in noise; it is not necessary to recognize the content or meaning of spoken words.


Proposals need not fulfill these requirements at this moment. Various types of proposals are widely welcome as long as they will possibly meet the requirements within approximately 1 to 2 years of additional development.
