A computer-implemented method for facilitating cross-language communication among users of respective wireless communication devices (101, 103; 201, 203; 301, 303; 400), the method comprising: - receiving, at a first of the wireless communication devices (101; 201; 301), a first user input indicating willingness to participate in a cross-language communication session with a second of the wireless communication devices; - receiving, at the second wireless communication device (103; 203; 303), a second user input indicating willingness to participate in the cross-language communication session with the first wireless communication device (101; 201; 301); - receiving, at the first wireless communication device (101; 201; 301), a first signal from a first sensor of the first wireless communication device; - receiving, at the second wireless communication device (103; 203; 303), a second signal from a second sensor of the second wireless communication device; - automatically comparing the first signal to the second signal to determine whether the first and the second signal satisfy a similarity criterion; - automatically establishing the cross-language communication session; and - if the cross-language communication session is established: - after receiving (600, 603) the first and second user inputs, receiving a first user message entered on the first wireless communication device (101; 201; 301) in a first natural language; - automatically generating a translated first user message, including translating the first user message into a second natural language, different than the first natural language; and - outputting the translated first user message on the second wireless communication device (103; 203; 303); - characterized in that the similarity criterion includes similarity of sounds received by the respective first and second wireless communication devices (101, 103; 201, 203; 301, 303; 400) and/or the similarity criterion includes similarity of images captured by the respective first and second wireless communication devices; - and in that automatically establishing the cross-language communication session is performed if the first and second signals satisfy the similarity criterion. - receiving, at a first of the wireless communication devices (101; 201; 301), a first user input indicating willingness to participate in a cross-language communication session with a second of the wireless communication devices; - receiving, at the second wireless communication device (103; 203; 303), a second user input indicating willingness to participate in the cross-language communication session with the first wireless communication device (101; 201; 301); - receiving, at the first wireless communication device (101; 201; 301), a first signal from a first sensor of the first wireless communication device; - receiving, at the second wireless communication device (103; 203; 303), a second signal from a second sensor of the second wireless communication device; - automatically comparing the first signal to the second signal to determine whether the first and the second signal satisfy a similarity criterion; - automatically establishing the cross-language communication session; and - if the cross-language communication session is established: - after receiving (600, 603) the first and second user inputs, receiving a first user message entered on the first wireless communication device (101; 201; 301) in a first natural language; - automatically generating a translated first user message, including translating the first user message into a second natural language, different than the first natural language; and - outputting the translated first user message on the second wireless communication device (103; 203; 303); - characterized in that the similarity criterion includes similarity of sounds received by the respective first and second wireless communication devices (101, 103; 201, 203; 301, 303; 400) and/or the similarity criterion includes similarity of images captured by the respective first and second wireless communication devices; - and in that automatically establishing the cross-language communication session is performed if the first and second signals satisfy the similarity criterion.
