Abstract

An apparatus comprising: a processor and memory including computer program code, the memory and the computer program code configured to, with the processor, cause the apparatus to: detect sound from an environment proximal to a device; determine a context of the device using the detected sound; and provide signaling to allow for selection of a context-specific service for use in navigation by the device based upon the result of the determined context.

Claims

1-36. -36. (canceled)

37. An apparatus comprising:

a processor and memory including computer program code, the memory and the computer program code configured to, with the processor, cause the apparatus to;

detect sound from an environment proximal to a device;

determine a context of the device using the detected sound; and

provide signaling to allow for selection of a context-specific service for use in navigation by the device based upon the result of the determined context.

38. The apparatus of claim 37, wherein the context is whether the device is located indoors or outdoors.

39. The apparatus of claim 38, wherein the context-specific service is at least one of:

a geographical positioning service and a map.

40. The apparatus of claim 39, wherein, if the device is determined to be located indoors, the geographical positioning service is at least one of the following:

a mobile phone network service, a wireless local area network service, a radio frequency identification service, a Bluetooth™

service, and a near field communication service and the map is a floor plan.

41. The apparatus of claim 37 wherein determination of the device context is performed by at least one of the following:

a) comparing the detected sound with at least one prerecorded sound stored in a database, and

b) comparing at least one audio feature extracted from the detected sound with at least one respective predetermined audio feature stored in a database.

42. The apparatus of claim 41, wherein comparison of the at least one audio feature extracted from the detected sound with at least one respective predetermined audio feature is performed using a classification method.

43. The apparatus of claim 42, wherein the classification method comprises at least one of the following:

K-nearest neighbours, hidden Markov modeling, dynamic time warping, and vector quantization.

44. The apparatus of claim 41 wherein the at least one audio feature comprises at least one of the following:

power spectra, zero crossing rate, short-time average energy, mel-frequency cepstral coefficients, mel-frequency delta cepstral coefficients, band energy, spectral centroid, bandwidth, spectral roll-off, spectral flux, linear prediction coefficients, and linear prediction cepstral coefficients.

45. The apparatus of claim 41, wherein at least one of the prerecorded sounds and the predetermined audio features are stored in the database according to at least one of time and location.

46. The apparatus of claim 37 wherein determination of the device context is performed at at least one of the device and a location remote to the device.

47. The apparatus of claim 37 wherein determination of the device context is performed at a database server located remote to the device.

48. The apparatus of claim 37 wherein determination of the device context using a echo of a test sound is performed by analyzing at least one characteristic of the echo.

49. The apparatus of claim 37, wherein the selection of the context-specific service is performed automatically by the device.

50. The apparatus of claim 49, wherein the selection is performed automatically only when a single context-specific service is available for selection.

51. A method, the method comprising:

detecting sound from an environment proximal to a device;

determining a context of the device using the detected sound; and

providing signaling to allow for selection of a context-specific service for use in navigation by the device based upon the result of the determined context.

52. A method, the method of claim 51 further comprising:

determining from the detected sound if the context is indoors or outdoors.

53. A method, the method of claim 52 further comprising:

determining from the context the navigation service to be selected for use.

54. A method, the method of claim 52 further comprising:

the determination of the device context is performed at a database server located remote to the device.

55. A non-transitory computer-readable memory medium storing a computer program, the computer program comprising computer code configured to perform the method of claim 53.

56. A database server, the database server configured to:

receive audio data associated with sound detected from an environment proximal to a device;

determine a context of the device using the received audio data; and

send the result of the determined context to allow for selection of a context-specific service for use in navigation by the device.

57. The database server of claim 56, wherein the audio data comprises at least one of an audio signal and an audio feature associated with the detected sound.
