Abstract (en)

[origin: WO0213498A2] The invention concerns a method for identifying a caller with a telephone service operator. The invention is characterised in that said method consists: for the operator, in making up at least a list of literal expressions and in attributing to the caller an identifier consisting of a combination of literal expressions taken consecutively from each of said lists; for the caller, in connecting himself to said telephone service and in speaking out, in sequence, each literal expression of said combination; for the operator, in identifying the caller by searching through voice recognition the combination of literal expressions attributed to the caller. The invention is useful for making secure access to telephone services.

[origin: WO0213498A2] The invention aims at solving the technical problem which consists in providing a method for identifying a caller from a telephone service operator, which would be more ergonomic than the known method, in particular concerning storage of the identifier, while ensuring enhanced security. The technical problem is solved by the method of the invention which consists: for the operator, in establishing at least a list of literal expressions and in attributing to the caller an identifier consisting of a combination of literal expressions taken consecutively from each of said lists; for the caller, in connecting himself to said telephone service and in speaking out, in sequence, each literal expression of said combination; for the operator, in identifying the caller by searching through voice recognition the combination of literal expressions attributed to the caller. The invention is useful for making secure access to telephone services. The inventive identification method is therefore based on voice recognition whereby in existing technologies, in particular, multispeaker flexible voice recognition, it is already possible to recognise a spoken literal expression among several thousands, with the only proviso that it is known in which list is found the expression to be identified. In general, a literal expression will consist of a single word or a meaningful set of words, such as All is well .
