A method for converting SMS or MMS into CRBT includes the following steps: the operational control center receives the text information, judges the format of received information and carries out corresponding format process to convert it into the information to be transformed. Information content authentication filters the sensitive vocabularies. If there is no sensitive word, user authentication is carried out to judge whether the user belongs to the custom on service. If it is not, it initiates software modules for error processing and sends a short message to tell the user how to be the customer, at the same time it generates an error log and transmits it to the customer database. If it is, it starts to convert the text information into a voice message through text-to-speech (TTS) system and synthesizes it with background music to CRBT standard audio files, which will be transmitted to the CRBT service provider or system operator then. |
