Abstract

A stand-alone, hand-held apparatus is provided, which combines elements of a scanning dictionary with an automatic-translation software, for in-context translation. Additionally, the apparatus may include a text-to-speech synthesis, for in-tandem exposure to spoken and translated forms of a portion of text, such as a clause, a sentence, or a few sentences. A whole document may thus be read, for example, sentence by sentence. The apparatus may further be used for teaching correct pronunciation of any portion of text, by recording the user'"'"'s pronunciation of the portion of text and comparing it with a text-to-speech synthesis produced by the apparatus.

Claims

1. A stand-alone, hand-held apparatus, which includes:

a sheath, having a proximal end with respect to a portion of text in a first language;

a scanner, located within said sheath, near said proximal end, arranged for scanning the portion of text, in the first language, wherein the portion of text is selected from the group consisting of al least one clause, at least one sentence, and at least two sentences;

a computerized system, located within said sheath, in communication with said scanner, arranged for performing;

i. an OCR conversion of the scanned text, in the first language; and

ii. an automatic translation to a second language, of the scanned text; and

at least one output system, in communication with said computerized system, for providing a translation in-context to a fragment of the portion of text, wherein the fragment is selected from the group consisting of a word and a phrase, and wherein said translation in-context to the fragment is based on said automatic translation.

2. The Apparatus according to claim 1, wherein said at least one output system includes an audio-output system.

3. The apparatus according to claim 1, wherein said at least one output system includes a visual display.

4. The apparatus according to claim 1, wherein said at least one output system is adapted for producing said automatic translation, in a complete form.

5. The apparatus according to claim 1, and further including a user interface system, in communication with said computerized system, for enabling a user to communicate with said apparatus.

6. The apparatus according to claim 1, wherein said computerized system is further arranged for performing a text-to-speech synthesis of the scanned text, and wherein said at least one output system is further adapted for audibly producing said text-to-speech synthesis.

7. A stand-alone, hand-held apparatus, which includes:

a sheath, having a proximal end with respect to a portion of text in a first language;

a scanner, located within said sheath near said proximal end, arranged for scanning the portion of text, in the first language, wherein the portion of text is selected from the group consisting of at least one clause, at least one sentence, and at least two sentences;

a computerized system, located within said sheath, in communication with said scanner, arranged for performing;

i. an OCR conversion of the scanned text, in the first language;

ii. a text-to-speech synthesis of the scanned text, in the first language; and

iii. an automatic translation to a second language, of the scanned text; and

at least one output system, in communication with said computerized system, for providing in-tandem exposure to spoken and translated forms of the portion of text.

8. The apparatus according to claim 7, wherein said at least one output system includes an audio-output system, and wherein said text-to-speech synthesis, in the first language, and said automatic translation, in the second language, are produced via said audio-output system, in sequence.

9. The apparatus according to claim 8, wherein said audio-output system includes an audio output rate control.

10. The apparatus according to claim 8, wherein said audio-output system includes a library of voices, from which a voice may be selected for an audio output.

11. The apparatus according to claim 8, wherein said audio-output system includes a library of voices, from which a first voice may be selected for said text-to-speech synthesis, and a second voice may be selected for said automatic translation.

12. The apparatus according to claim 7, wherein said at least one output system includes an audio output system and a visual display, and wherein said text-to-speech synthesis, in the first language, is produced audibly, and said automatic translation, in the second language, is displayed.

13. The apparatus according to claim 7, wherein said at least one output system is further adapted for producing a translation in-context of a fragment of the portion of text, wherein the fragment is selected from the group consisting of a word and a phrase, and wherein said translation in-context is based on said automatic translation.

14. The apparatus according to claim 7, and further including a user interface system, in communication with said computerized system, for enabling a user to communicate with said apparatus.

15. The apparatus according to claim 7, and further including a microphone, wherein said computerized system is further arranged for recording speech.

16. The apparatus according to claim 7, wherein said apparatus may be further arranged for performing an OCR conversion and a text-to-speech synthesis of a portion of text in the second language, and an automatic translation to the first language.

17. A method of providing in-tandem exposure to spoken and translated forms of a portion of text, said method including:

scanning a portion of text, selected from the group consisting of at least one clause, at least one sentence, and at least two sentences;

performing an OCR conversion of the scanned text, in a first language;

performing a text-to-speech synthesis of the scanned text in the first language;

producing an audio output of said text-to-speech synthesis, in the first language;

performing an automatic translation of the scanned text, to a second language;

producing an output of said automatic translation, in the second language, thus providing said in-tandem exposure to spoken and translated forms of the portion of text.

18. A stand-alone, hand-held apparatus for teaching correct pronunciation, which includes:

a sheath, having a proximal end with respect to a portion of text;

a scanner, located within said sheath, near said proximal end, arranged for scanning the portion of text;

a computerized system, located within said sheath, in communication with said scanner, arranged for performing an OCR conversion and a text-to-speech synthesis of the scanned text;

a microphone and an audio recording system, in communication with said computerized system, for recording a user'"'"'s pronunciation of the scanned text;

an audio-output system, in communication with said computerized system, for producing audio outputs of said text-to-speech synthesis and of the user'"'"'s pronunciation of the scanned text;

a signal evaluation software, for comparing said text-to-speech synthesis and the user'"'"'s pronunciation of the scanned text, and

a display, for displaying an output of said signal evaluation software.

19. A method for teaching correct pronunciation, which includes:

scanning a portion of text, selected from the group consisting of at least one clause, at least one sentence, and at least two sentences;

performing an OCR conversion to the scanned text;

performing a text-to-speech synthesis of the scanned text;

producing an audio output of the text-to-speech synthesis;

recording a user'"'"'s pronunciation of the scanned text;

playing back the user'"'"'s pronunciation of the scanned text; and

comparing the user'"'"'s pronunciation of the scanned text with the audio output of the text-to-speech synthesis.

20. The method of claim 19, wherein comparing includes comparing audibly.

21. The method of claim 19, wherein comparing includes comparing by a signal evaluation software.

22. A method for providing a translation in-context, which includes:
