1. A broadcast signal receiver comprising: a text data receiver configured to receive broadcast text data and to transmit the broadcast text data to a user interface, wherein the broadcast text data includes at least one word; a text-to-speech (TTS) converter configured to convert received text data into an audio speech sound, wherein the TTS converter is configured to: detect whether the at least one word is also included in a stored list of words, and when the at least one word is also included in the stored list of words, convert the at least one word according to a conversion defined by the stored list, and when the at least one word is not included in the stored list of words, convert the at least one word according to a set of predetermined conversion rules; a conversion memory configured to store the list of words as initial data; an update receiver configured to receive, from a conversion repository, and via a network connection, update data, wherein the update data includes updated words, associated conversions, and updated conversion rules, and configured to store, in the conversion memory, the update data; and a commander circuitry configured to control an operation of the broadcast signal receiver, wherein the commander circuitry is configured to receive a user control input, wherein the user control input indicates an incorrect conversion carried out by the TTS converter; and wherein the broadcast signal receiver is configured to, in response to the user control input, send a message to a data provider, and thereby request update data, wherein the message indicates a conversion problem and indicates text which was converted, by the TTS converter, into speech.
