Definitions

  • the invention relates to a method for the acoustic output of text.
  • Nisus ® Writer a word processor from Nisus Software, Inc., is known for providing spoken text or "reading aloud" of written text.
  • a separate speech-to-speech algorithm is available for each language in which a text can be acoustically output. Such an algorithm converts characters into consecutive phonemes or syllables. The user can select the appropriate language conversion algorithm from a menu for a particular language. If the text is in a language for which the speech conversion algorithm is not determined, the speech output is not intelligible.
  • the safety advantage for a driver which lies in the acoustic output of a text, at least partially if the driver first has to check the language of the text and then has to search for and select the appropriate language conversion algorithm.
  • a telephone subscriber messaging system in which a voice mail system is coupled to an e-mail system. E-mails can be issued acoustically to a participant. In order to be able to select the correct speech conversion algorithm for the speech output, e-mails are examined for letter combinations with three consecutive letters. Due to the frequency of occurrence of the letter combinations conclusions about the language used are drawn. This process requires considerable effort for the implementation of the system. It must be provided in such a system considerable resources of memory and processing power for the program flow and for corresponding libraries. This is undesirable especially in automotive applications. In addition, a reliable distinction between similar languages is particularly problematic when the news is short and enriched with other language terms.
  • the patent GB 2 318 659 A discloses a method of determining a natural language based on the frequency of character pairs in common words of a natural language.
  • a text is examined for words or abbreviations that are characteristic of a language in order to identify the language of the text. Due to the recognized language, an algorithm specifically assigned to the recognized language is automatically selected for the acoustic output of the text. This correctly emphasizes the synthetically generated phonemes, or the syllables or sounds.
  • a written text about broadcasting or mobile communications in particular a mobile phone, e.g. B. via the Radio Data System (RDS) or mobile via Short Message Service (SMS), in a passenger car
  • the text can be played without operator action of the driver in the appropriate speech for the language of the text. This is particularly important for business travelers who also maintain contacts with foreign-language customers.
  • RDS Radio Data System
  • SMS Short Message Service
  • FIG. 1 illustrated voice output system is integrated into a multifunction control panel of a motor vehicle, with which a car radio, a mobile phone, a navigation system and an air conditioner are controlled.
  • a microprocessor 1 has a text memory 2, which is a RAM. Via a telephone module or a mobile radio unit 3, the microprocessor 1 wirelessly messages receive, such as an e-mail or a fax.
  • a user can, by operating a single control, for example a push-button marked with the letter "E", cause the microprocessor 1 to connect to his mailbox at the ISP and retrieve incoming e-mails. The received text is then stored in the text memory 2 and output without further action of the user.
  • a single control for example a push-button marked with the letter "E”
  • the mobile radio unit 3 receives a fax
  • the text contained in the fax as pixels is converted by a text recognition software into words with defined characters in order to be stored in the text memory 2.
  • the microprocessor 1 successively loads the words stored in the text memory 2 and converts them into digitized phonemes, that is, into a succession of sounds or word syllables.
  • the digitized phonemes are output to an output system consisting of a digital / analog converter 4, an audio amplifier 5 and at least one loudspeaker 6.
  • the digital / analog converter 4 converts the digitized phonemes into analog voice signal amplified by the audio amplifier 5 to a user-desired volume and reproduced acoustically by the loudspeaker 6.
  • the microprocessor 1 examines a text for the occurrence of keywords and typical letter combinations in those languages in each of which it has a speech conversion algorithm.
  • keywords include salutations and salutations such as “Dear”, “Mr.”, “Mrs.”, “Dear”, “Cher”, “Chère”, etc.
  • Further Articles, pronouns, and conjunctions are words that easily identify a language. The same applies to typical character combinations or abbreviations such as "H.”, "Mr.”, “F.”, “Fr.”, “Mr.”, “Ms.”, “M.”, “Mme”.
  • the microprocessor since sometimes the salutation and the subsequent text are held in different languages, the microprocessor, after having been able to associate the first keyword or the first typical character combination with a concrete language, continues its search in the text. If contradictions occur, so that more than one language is recognized on the basis of the identified characteristic words or characters, a majority decision is made. The speech output is then made in the language most frequently recognized in the text. Thus spelling errors do not lead to a misinterpretation of the language.
  • FIG. 2 shows a voice output system, in which a digital signal processor 7 and a screen 8 for additional optical information output are additionally provided.
  • the mobile radio unit 3 receives a text message and transfers it to the microprocessor 1. This forwards the text into the text memory 2.
  • the digital signal processor 7 examines the text for characteristic words and character combinations in the available languages and selects the associated language conversion algorithm for speech conversion.
  • the synthetically generated phonemes are the signal processor 7 to the output system 4, 5, 6 on.
  • the digital signal processor 7 carries out text recognition in order first to check the language of the text and to convert the recognized characters into phonemes.
