A sound collection method comprising:

• a procedure of collecting sound by a sound collection unit including a microphone;
• a procedure of determining noise in dictation based on voice collected by the sound collection unit;
• and
• a presentation procedure of performing presentation based on a determination result of the noise.

A recording medium recording a sound collection program configured to cause a computer to execute:

• a procedure of collecting sound by a sound collection unit including a microphone;
• a procedure of determining noise in dictation based on voice collected by the sound collection unit;
• and
• a presentation procedure of performing presentation based on a determination result of the noise.

A dictation method comprising:

• a procedure of reading, from a recording unit recording first sound collected by a sound collection unit, second sound acquired by performing noise reduction processing on the collected first sound, and information of noise in a duration of sound collection by the sound collection unit, the second sound and generating a document by performing first dictation processing through voice recognition of the read second sound;
• a procedure of generating, when the document cannot be generated by the first dictation processing, a document by reading the second sound and the noise information and performing second dictation processing through voice recognition of third sound acquired by adding noise based on the noise information to the read second sound;
• and
• a procedure of generating, when the document cannot be generated by the second dictation processing, a document by performing third dictation processing through voice recognition of fourth sound acquired by performing noise reduction processing on the read first sound.
