Abstract

A speech synthesis apparatus includes a content selection unit that selects a text content item to be converted into speech; a related information selection unit that selects related information which can be at least converted into text and which is related to the text content item selected by the content selection unit; a data addition unit that converts the related information selected by the related information selection unit into text and adds text data of the text to text data of the text content item selected by the content selection unit; a text-to-speech conversion unit that converts the text data supplied from the data addition unit into a speech signal; and a speech output unit that outputs the speech signal supplied from the text-to-speech conversion unit.

Claims

1. A speech synthesis apparatus comprising:

a content selection unit that selects a text content item to be converted into speech;

a related information selection unit that selects related information which can be at least converted into text and which is related to the text content item selected by the content selection unit;

a data addition unit that converts the related information selected by the related information selection unit into text and adds text data of the text to text data of the text content item selected by the content selection unit;

a text-to-speech conversion unit that converts the text data supplied from the data addition unit into a speech signal; and

a speech output unit that outputs the speech signal supplied from the text-to-speech conversion unit.

2. The speech synthesis apparatus according to claim 1,

wherein the related information selection unit selects music data related to the selected text content item, and

the speech output unit mixes the speech signal supplied from the text-to-speech conversion unit and a music signal of the music data and outputs a resulting signal.

3. The speech synthesis apparatus according to claim 1 or claim 2,

wherein the related information selection unit selects the related information which is related to the text content item selected by the content selection unit from among a plurality of pieces of related information which are related to a plurality of text content items capable of being selected by the content selection unit and which are recorded in advance.

4. The speech synthesis apparatus according to claim 1 or claim 2,

wherein the content selection unit selects a desired text content item from among a plurality of text content items on a network, and

the related information selection unit selects the related information which is related to the text content item selected by the content selection unit from among a plurality of pieces of related information which are related to a plurality of text content items capable of being selected by the content selection unit and which are stored on a network.

5. A speech synthesis method comprising the steps of:

selecting a text content item to be converted into speech, the text content item being selected by a content selection unit;

selecting related information which can be at least converted into text and which is related to the text content item selected by the content selection unit, the related information being selected by a related information selection unit;

converting the related information selected by the related information selection unit into text and adding text data of the text to text data of the text content item selected by the content selection unit, the conversion and addition being performed by a data addition unit;

converting text data supplied from the data addition unit into a speech signal, the conversion being performed by a text-to-speech conversion unit; and

outputting the speech signal supplied from the text-to-speech conversion unit, the speech signal being output by a speech output unit.

6. The speech synthesis method according to claim 5, further comprising the steps of:

selecting music data related to the selected text content item, the music data being selected by the related information selection unit; and

mixing the speech signal supplied from the text-to-speech conversion unit and a music signal of the music data and outputting a resulting signal, the mixing and outputting being performed by the speech output unit.

7. A speech synthesis program causing a computer to function as:

a content selection unit that selects a text content item to be converted into speech;

a related information selection unit that selects related information which can be at least converted into text and which is related to the text content item selected by the content selection unit;

a data addition unit that converts the related information selected by the related information selection unit into text and adds text data of the text to text data of the text content item selected by the content selection unit;

a text-to-speech conversion unit that converts text data supplied from the data addition unit into a speech signal; and

a speech output unit that outputs the speech signal supplied from the text-to-speech conversion unit.

8. The speech synthesis program according to claim 7,

wherein the related information selection unit selects music data related to the selected text content item, and

the speech output unit mixes the speech signal supplied from the text-to-speech conversion unit and a music signal of the music data and outputs a resulting signal.

9. A portable information terminal comprising:

a command input unit that obtains a command input by a user;

a content selection unit that selects a text content item to be converted into speech in accordance with the command input by the user;

a related information selection unit that selects related information which can be at least converted into text and which is related to the text content item selected by the content selection unit;

a data addition unit that converts the related information selected by the related information selection unit into text and adds text data of the text to text data of the text content item selected by the content selection unit;

a text-to-speech conversion unit that converts text data supplied from the data addition unit into a speech signal; and

a speech output unit that outputs the speech signal supplied from the text-to-speech conversion unit.

10. The portable information terminal according to claim 9,

wherein the related information selection unit selects music data related to the selected text content item, and

the speech output unit mixes the speech signal supplied from the text-to-speech conversion unit and a music signal of the music data and outputs a resulting signal.

11. A speech synthesis system comprising:

a selection and addition apparatus that selects a text content item to be converted into speech in accordance with a command input by a user, selects related information which can be at least converted into text and which is related to the selected text content item, converts the selected related information into text, and adds text data of the text to text data of the selected text content item in accordance with the command input by the user;

a text-to-speech conversion apparatus that converts the text data supplied from the selection and addition apparatus into a speech signal; and

a speech output apparatus that outputs, into the air, speech corresponding to the speech signal supplied from the text-to-speech conversion apparatus.

12. The speech synthesis system according to claim 11,

wherein the selection and addition apparatus selects music data related to the selected text content item, and

the speech output apparatus mixes the speech signal supplied from the text-to-speech conversion apparatus and a music signal of the music data and outputs speech according to a mixed speech signal.

13. The speech synthesis system according to claim 11,

wherein the selection and addition apparatus selects a music signal related to the selected text content item, and

the speech output apparatus includes a device that outputs, into the air, speech according to the speech signal supplied from the text-to-speech conversion apparatus and a device that outputs, into the air, music according to the music signal supplied from the selection and addition apparatus.
