Testing speech recognition systems using test data generated by text-to-speech conversion

Apparatus for testing speech recognition systems, the apparatus comprising:

• at least one processor operative to:
• (a) generate and store a digital audio file from a reference text using a text-to-speech process;
• and (b) read the digital audio file using a speech recognition process to generate a decoded text representative of the reference text.

An article of manufacture for testing speech recognition systems, comprising a machine readable medium containing one or more programs which when executed implement the steps of:

• a) generating a digital audio file from a reference text using a text-to-speech device, the digital audio file being stored within a storage area of a computer system;
• and
• b) reading the digital audio file using a speech recognition device to generate a decoded text representative of the reference text.

A method for testing speech recognition systems, the method comprising the steps of:

• a) generating a synthetic speech from a reference text using a text-to-speech device;
• and
• b) processing the synthetic speech using a speech recognition device to generate a decoded text representative of the reference text.

Apparatus for testing speech recognition systems, the apparatus comprising:

• at least one processor operative to generate a synthetic speech from a reference text using a text-to-speech process;
• and
• at least a second processor operative to process the synthetic speech using a speech recognition process to generate a decoded text representative of the reference text.
