Abstract

Fixed-format and coded control informations are received for generating announcements. The coded control informations select synthetic speech information items from a store. A speech generator under control of the control items forms a composite speech message. For a message containing both fixed items and variable items, fixed items are encoded in enriched phoneme notation. Variable items are encoded in straight phoneme notation. Items are provided in multiple versions. Each version has a respective different prosody pattern of pitch and/or rhythm of its phoneme sequence, and is selected by a multivalued context symbol adjoined or implicit to the associated control information element.

Claims

1. A device for generating speech message information, said device comprising input means for receiving fixed-format and coded control information elements, a storage unit for storing synthetic speech information items that are selectable in sequence by said coded control information elements, and a speech generator for under control of said speech information items generating a composite speech message,

characterized in that for a message format containing both fixed items and variable items, such fixed items are encoded in enriched phoneme notation and each variable item is encoded as straight phoneme notation, together with lexical accents, and a particular pattern of timing and prosody for at least one variable item is selectable from a set of standard patterns in dependence solely upon a context of the variable item indicated by a multivalued context symbol adjoined to or implicit in an associated control information element.

2. A device as claimed in claim 1, wherein said input means comprise broadcast reception means, and said fixed-format control elements are represented by a message code and one or more code items respectively indicating all said variable items in the message.

3. A device as claimed in claim 2, for representing traffic information messages in a vehicle, said device furthermore having selection means for selectively, under control of an actual vehicle state, selecting among said messages to be generated or suppressed.

7. A device as claimed in claim 1, for representing traffic information messages in a vehicle, said device furthermore having selection means for selectively, under control of an actual vehicle state, selecting among said messages to be generated or suppressed.

8. A device as claimed in claim 1, wherein said storage unit comprises a storage carrier that can reversibly be joined with said device, as accommodating at least all actual said variable message items.

4. A vehicle provided with a device for generating speech message information, the vehicle comprising broadcast means for receiving fixed-format and coded control information elements, a storage unit for storing synthetic speech information items that are selectable in sequence by said coded control information elements, and a speech generator for under control of said speech information items generating a composite speech message,

characterized in that for a message format containing both fixed items and variable items, such fixed items are encoded in enriched phoneme notation and each variable item is encoded as straight phoneme notation, together with lexical accents, and a particular pattern of timing and prosody for at least one variable item is selectable from a set of standard patterns in dependence solely upon a context of the variable item indicated by a multivalued context symbol adjoined to or implicit in an associated control information element.

5. A vehicle as claimed in claim 4, wherein said storage unit comprises a storage carrier that can reversibly be joined with said device, as accommodating at least all actual said variable message items.

6. An encoding device for encoding a composite speech message for transmitting for controlling the generating of speech message information, under control of fixed-format and coded control information elements, by means of a storage unit for storing synthetic speech information items that are selectable in sequence by said coded control information elements, for ultimate representation as a composite speech message,

characterized in that for a message format containing both fixed items and variable items, the fixed items are encoded in enriched phoneme notation and each variable item is encoded in straight phoneme notation, together with lexical accents, and a particular pattern of timing and prosody for at least one variable item is selectable from a set of standard patterns in dependence solely upon a context of the variable item indicated by a multivalued context symbol adjoined to or implicit in an associated control information element.
