Abstract

In order to provide a practical E-mail reader for reading out E-mails phonetically enabling easy grasping of their contents by a user with its vocal output even when quotation codes or header information are included in the E-mails, a phonetic E-mail reader of the invention comprises a speech synthesizer (102) for converting text data into vocal data, quotation code storing means (105) for storing quotation codes used for indicating a quotation line inserted at a top of the quotation line, and quotation code elimination means (106) for detecting and eliminating a quotation code inserted at tops of quotation lines referring to the quotation code storing means (105) before supplying the quotation lines to the speech synthesizer (102).

Claims

1. A phonetic E-mail reader comprising:

a speech synthesizer for converting text data delivered thereto into vocal data corresponding to said text data;

quotation code storing means for storing quotation codes used for indicating a quotation line in an E-mail text, said quotation codes being found at a top of said quotation line, said E-mail text including communication lines not having quotation codes; and

quotation code elimination means for detecting and eliminating at least one of said quotation codes inserted at tops of quotation lines in E-mail texts referring to said quotation code storing means, and for passing on communication lines and quotation lines with said quotation codes eliminated to said speech synthesizer to be converted into vocal data corresponding thereto.

2. A phonetic E-mail reader as recited in claim 1, wherein:

said quotation code eliminating means eliminates said at least one of said quotation codes, together with at least one blank code following said at least one of said quotation codes.

3. A phonetic E-mail reader as recited in claim 1, wherein:

said quotation code elimination means eliminates said at least one of said quotation codes, together with at least one character code following said at least one of said quotation codes and preceding any character code other than blank codes and said quotation codes.

4. A phonetic E-mail reader as recited in claim 1, wherein:

said quotation code elimination means operates in an omitting mode for eliminating said at least one of said quotation codes together with all character codes of said quotation lines.

5. A phonetic E-mail reader recited in claim 1, further comprises:

a header elimination means for eliminating header information from an E-mail before supplied to said quotation code elimination means when said header information is added to said E-mail text through network delivering.

6. A phonetic E-mail reader as recited in claim 1, further comprising:

communication parameter storing means for storing values of parameters to be delivered to said speech synthesizer for determining features of vocal data into which said communication lines are to be converted;

quotation parameter storing means for storing values of parameters to be delivered to said speech synthesizer for determining features of vocal data into which quotation lines are to be converted; and

a selector for selecting said communication parameter storing means for delivering parameter values stored therein to said speech synthesizer when said communication lines are supplied to said speech synthesizer, and for selecting said quotation parameter storing means for delivering parameter values stored therein to said speech synthesizer, when said quotation lines are supplied to said speech synthesizer, said selector being controlled by said quotation code elimination means.

7. A phonetic E-mail reader in claim 6, wherein:

said features of vocal data include at least one of voice sex, reading speed, tone, intonation and loudness of said vocal data.

8. A phonetic E-mail reader as recited in claim 1, wherein adjacent quotation lines form a quotation paragraph and wherein said quotation code elimination means inserts a beginning signal at a beginning of a quotation paragraph and an ending signal at an end of a quotation paragraph, said phonetic E-mail reader further comprising:

notification message storing means for storing a beginning message for notifying a beginning of each of said quotation paragraphs, and for storing an ending message for notifying an ending of each of said quotation paragraphs; and

a read-out controller for replacing said beginning signal with said beginning message stored in said notification message storing means, and for replacing said ending signal with said ending message stored in said notification message storing means.

9. A phonetic E-mail reader as recited in claim 8, wherein adjacent communication lines form a communication paragraph, said phonetic E-mail reader further comprising:

text parameter storing means for storing values of parameters to be delivered to said speech synthesizer for determining features of vocal data into which said communication paragraphs and said quotation paragraphs are to be converted;

notification parameter storing means for storing values of parameters to be delivered to said speech synthesizer for determining features of vocal data into which said beginning message and said ending message are to be converted; and

a selector for selecting said text parameter storing means for delivering parameter values stored therein to said speech synthesizer when either of said communication paragraphs and said quotation paragraphs are supplied to said speech synthesizer, and for selecting said notification parameter storing means for delivering parameter values stored therein to said speech synthesizer when either of said beginning message and said ending message are supplied to said speech synthesizer, said selector being controlled by said read-out controller.

10. A phonetic E-mail reader recited in claim 9, wherein:

said features of vocal data include at least one of voice sex, reading speed, tone, intonation and loudness of said vocal data.

11. A phonetic E-mail reader as recited in claim 8, wherein said quotation code elimination means operates in a omitting mode for eliminating said at least one of said quotation codes together with all character codes of said quotation lines and for inserting an omitting signal in place of each of said quotation paragraphs;

said notification message storing means further store an omitting message for notifying omission of each of said quotation paragraphs eliminated; and

said read-out controller replaces said omitting signal with said omitting message stored in said notification message storing means.

12. A phonetic E-mail reader recited in claim 11, further comprising:

text parameter storing means for storing values of parameters to be delivered to said speech synthesizer for determining features of vocal data into which said communication paragraphs are to be converted;

notification parameter storing means for storing values of parameters to be delivered to said speech synthesizer for determining features of vocal data into which said omitting message are to be converted; and

a selector for selecting said text parameter storing means for delivering parameter values stored therein to said speech synthesizer when said communication paragraphs are supplied to said speech synthesizer, and selecting said notification parameter storing means for delivering parameter values stored therein to said speech synthesizer when said omitting messages are supplied to said speech synthesizer, controlled by said read-out controller.

13. A phonetic E-mail reader recited in claim 12, wherein:

said features of vocal data include at least one of voice sex, reading speed, tone, intonation and loudness of said vocal data.
