Speech synthesis dictionary creating device and method

A speech synthesis dictionary creating device comprising:

• a processing circuitry coupled to a memory, the processing circuitry being configured to:
• receive input of first speech data;
• receive input of second speech data;
• detect authentication information included in the second speech data;
• output third speech data in which the authentication information is detected;
• and
• create a speech synthesis dictionary using the first speech data and using a text corresponding to the first speech data upon determining that a speaker of the first speech data is the same as a speaker of the third speech data.

A speech synthesis dictionary creating method comprising:

• receiving input of first speech data;
• selecting at least one text from texts stored in a memory;
• present the selected text for a user to recognize and utter the selected text;
• receiving input of second speech data which is considered to be speech data obtained by uttering of the presented text;
• and
• creating a speech synthesis dictionary using the first speech data and using a text corresponding to the first speech data upon determining that a speaker of the first speech data is the same as a speaker of the second speech data.
