Definitions

  • This application relates to hearing assistance systems, and more particularly, to hearing assistance systems with own voice detection.
  • Hearing assistance devices are electronic devices that amplify sounds above the audibility threshold to is hearing impaired user. Undesired sounds such as noise, feedback and the user's own voice may also be amplified, which can result in decreased sound quality and benefit for the user. It is undesirable for the user to hear his or her own voice amplified. Further, if the user is using an ear mold with little or no venting, he or she will experience an occlusion effect where his or her own voice sounds hollow ("talking in a barrel"). Thirdly, if the hearing aid has a noise reduction/environment classification algorithm, the user's own voice can be wrongly detected as desired speech.
  • a digital sound processing system 308 processes the acoustic signals received by the first and second microphones, and provides a signal to the receiver 306 to produce an audible signal to the wearer of the device 305.
  • the illustrated digital sound processing system 308 includes an interface 307, a sound processor 308, and a voice detector 309.
  • the illustrated interface 307 converts the analog signals from the first and second microphones into digital signals for processing by the sound processor 308 and the voice detector 309.
  • the interface may include analog-to-digital converters, and appropriate registers to hold the digital signals for processing by the sound processor and voice detector.
  • the voice detector 309 receives signals representative of sound received by the first microphone and sound received by the second microphone.
  • the voice detector 309 detects the user's own voice, and provides an indication 311 to the sound processor 308 regarding whether the user's own voice is detected. Once the user's own voice is detected any number of possible other actions can take place.
  • the sound processor 308 can perform one or more of the following, including but not limited to reduction of the amplification of the user's voice, control of an anti-occlusion process, and/or control of an environment classification process. Those skilled in the art will understand that other processes may take place without departing from the scope of the present subject matter.
  • the illustrated power analyzer 413 compares the power of the error signal 420 to the power of the signal representative of sound received from the first microphone. According to various embodiments, a voice will not be detected unless the power of the signal representative of sound received from the first microphone is much greater than the power of the error signal. For example, the power analyzer 413 compares the difference to a threshold, and will not detect voice if the difference is less than the threshold.
  • the illustrated coefficient analyzer 414 analyzes the filter coefficients from the adaptive filter process 415. According to various embodiments, a voice will not be detected unless a peak value for the coefficients is significantly high. For example, some embodiments will not detect voice unless the largest normalized coefficient is greater than a predetermined value (e.g. 0.5).
  • a predetermined value e.g. 0.5
  • FIGS. 5-7 illustrate various processes for detecting voice that can be used in various embodiments of the present subject matter.
  • the power of the error signal from the adaptive filter is compared to the power of a signal representative of sound received by the first microphone.
  • the threshold is selected to be sufficiently high to ensure that the power of the first microphone is much greater than the power of the error signal.
  • voice is detected at 523 if the power of the first microphone is greater than the power of the error signal by a predetermined threshold, and voice is not detected at 524 if the power of the first microphone is greater than the power of the error signal by a predetermined threshold.
  • coefficients of the adaptive filter are analyzed.
  • voice is detected at 623 if the largest normalized coefficient is greater than a predetermined value, and voice is not detected at 624 if the largest normalized coefficient is not greater than a predetermined value.
  • the power of the error signal from the adaptive filter is compared to the power of a signal representative of sound received by the first microphone.
  • voice is not detected at 724 if the power of the first microphone is not greater than the power of the error signal by a predetermined threshold. If the power of the error signal is too large, then the adaptive filter has not converged.
  • the coefficients are not analyzed until the adaptive filter converges.
  • coefficients of the adaptive filter are analyzed if the power of the first microphone is greater than the power of the error signal by a predetermined threshold.
  • FIG. 8 illustrates one embodiment of the present subject matter with an "own voice detector" to control active noise canceller for occlusion reduction.
  • the active noise canceller filters microphone M2 with filter h and sends the filtered signal to the receiver.
  • the microphone M2 and the error microphone M3 (in the ear canal) are used to calculate the filter update for filter h.
  • the own voice detector which uses microphone M1 and M2, is used to steer the stepsize in the filter update.
  • FIG. 9 illustrates one embodiment of the present subject matter offering a multichannel expansion, compression and output control limiting algorithm (MECO) which uses the signal of microphone M2 to calculate the desired gain and subsequently applies that gain to microphone signal M2 and then sends the amplified signal to the receiver. Additionally, the gain calculation can take into account the outcome of the own voice detector (which uses M1 and M2) to calculate the desired gain. If the wearer's own voice is detected, the gain in the lower channels (typically below 1 KHz) will be lowered to avoid occlusion. Note: the MECO algorithm can use microphone signal M1 or M2 or a combination of both.
  • MECO multichannel expansion, compression and output control limiting algorithm
  • FIG. 10 illustrates one embodiment of the present subject matter which uses an "own voice detector" in an environment classification scheme. From the microphone signal M2, several features are calculated. These features together with the result of the own voice detector, which uses M1 and M2, are used in a classifier to determine the acoustic environment. This acoustic environment classification is used to set the gain in the hearing aid.
  • the hearing aid may use M2 or M1 or M1 and M2 for the feature calculation.
