Abstract

In a method and apparatus for wireless transmission of messages between a vehicle-internal communication system and a vehicle-external central computer, the vehicle-internal communication system has acoustic output unit for the playback of a received message. In the vehicle-external central computer, the message, which is at first present in text form and is to be sent to the vehicle-internal communication system, is transformed into a phonetic transcription; the phonetic transcription, is then transmitted to the vehicle-internal communication system. In the vehicle internal communication system, the phonetic transcription is transformed to speech and is emitted via the acoustic output unit. Spoken messages from a vehicle occupant are recorded via an acoustic input unit, processed and transmitted to the central computer by reversal of the same process.

Claims

1. Process for wireless transmission of electronic and spoken mail messages between a vehicle-external central computer and a vehicle-internal communication system, comprising:

presenting an electronic mail message to said central computer;

transforming in said central computer the text message into a phonetic transcription;

transmitting the phonetic transcription of an electronic mail message to the vehicle-internal communication system;

then in the vehicle internal communication system, transforming the phonetic transcription to speech;

emitting the message as audible speech via the acoustic output unit; and

transmitting a spoken message to said central computer by transforming the spoken message into a phonetic transcription in the vehicle internal communication system, which transcription is then sent by wireless communication to said central computer.

2. A process for wireless transmission of electronic mail messages between a vehicle-external central computer and a vehicle-internal communication system having an acoustic output unit for the playback of a received electronic mail message which is at first present in text form in the vehicle-external central computer, comprising

said central computer transforming the text message into a phonetic transcription;

transmitting the phonetic transcription to the vehicle-internal communication system;

in the vehicle-internal communication system, transforming the phonetic transcription to speech; and

emitting the message as audible speech via the acoustic output unit,

wherein the vehicle-internal communication system also has an acoustic input unit for recording a spoken message, and further comprising;

transforming a spoken electronic mail message in the vehicle-internal communication system to a phonetic transcription;

transmitting the phonetic transcription to the vehicle-external central computer; and

said central computer transforming the phonetic transcription to text for storage or processing it in text form.

3. A method for delivering textual messages to a vehicle occupant in audible form and from the vehicle occupant in spoken form, comprising:

processing a textual electronic mail message in a data processor situated externally to said vehicle to generate a phonetic transcription thereof;

transmitting said phonetic transcription to said vehicle via a wireless communications medium;

processing said phonetic transcription on board the vehicle to generate speech signals;

emitting said speech signals in audible form via an acoustic output unit; and

transmitting a spoken message to said central computer by transforming the spoken message into a phonetic transcription in the vehicle internal communication system, which transcription is then sent by wireless communications to said central computer.

4. Apparatus for delivering textual electronic mail messages to a vehicle occupant in audible form and from the vehicle occupant in spoken form, comprising:

a vehicle-external data processor programmed to translate a textual electronic mail message into a phonetic transcription;

a wireless communication link for transmitting the phonetic transcription to the vehicle;

a device situated on board the vehicle, for transforming the phonetic transcription to speech signals;

an acoustic output unit coupled to receive said speech signals and generate audible speech corresponding thereto; and

transmitting a spoken message to the vehicle-external data processor by transforming the spoken message into a phonetic transcription on board the vehicle and forwarding the phonetic transcription via the wireless communications link to the vehicle-external data processor.

5. A method for acoustic delivery to a vehicle occupant of textual electronic mail messages generated externally to the vehicle and of messages spoken by an occupant in a vehicle, comprising:

translating said textual message into a phonetic transcription thereof;

processing said phonetic transcription to generate speech signals;

emitting said speech signals in acoustic form via an acoustic output unit;

performing said translating step in a stationary data processor external to the vehicle;

transmitting said phonetic transcription from said data processor to the vehicle via a wireless transmission line;

said processing and emitting steps are performed on board the vehicle; and

transmitting a spoken message to said data processor by transforming the spoken message into a phonetic transcription on board the vehicle and forwarding the transcription via the transmission line to said data processor.

6. A method for transmitting to a recipient situated external to a vehicle, a textual electronic mail message corresponding to an audible message spoken by a vehicle occupant, comprising:

recording acoustic speech signals comprising said spoken electronic mail message;

processing said acoustical speech signals to generate a phonetic transcription corresponding thereto; and

translating said phonetic transcription into a textual message in a data processor;

wherein

said recording and processing steps are performed on board the vehicle;

said phonetic transcription is transmitted from said vehicle to said data processor via a wireless transmission link; and

said translating step is performed externally to the vehicle.

7. Apparatus for transmitting to a recipient situated external to a vehicle of an electronic mail message generated in spoken form by a vehicle occupant, comprising:

a transducer situated on board the vehicle for transforming audible speech to electrical speech signals;

a processor situated on board the vehicle for transforming said electrical speech signals into a phonetic transcription corresponding thereto;

a data processor situated at a point external to the vehicle and programmed to translate said phonetic transcription to a textual message; and

a wireless communication link for transmitting said phonetic transcription from said vehicle to said data processor.
