Abstract: A key pair validation method provides for a first party to generate a seed to define a private key, a public key, a session key and a validation field for the purpose of performing a cryptographic activity with a second party. The validation field is determined by encrypting the first party seed. The second party receives the first party public key and the validation field from the first party. The second party calculates a session key and utilizing the calculated session key, decrypts a cipher text to recover the first party's seed and the first party's private and public key. The recovered first party public key is compared to the received first party public key. If the received and recovered public keys match, the private-public key pair received from the first party is validated and the second party proceeds with the cryptographic task. If the received and recovered public keys do not match, the second party simply reports to the first party that the cryptographic task failed.

Abstract: Method of recognizing phones in speech of any language. Acquire phones for all languages and a set of languages. Acquire a pronunciation dictionary, a transcript of speech for the set of languages, and speech for the transcript. Receive speech containing unknown phones. If the speech's language is unknown, compare it to the phones for all languages to determine the phones. If the language is known but no phones were acquired in that language, compare the speech to the phones for all languages to determine the phones. If phones were acquired in the speech's language but no corresponding pronunciation dictionary was acquired, compare the speech to the phones for all languages to determine the phones. If a pronunciation dictionary was acquired for the phones in the speech's language but no transcript was acquired then compare the speech to the phones for all languages to determine the phones.
