A voice spelling method. A voice spelling method can include the steps of: in an audio-only interface, receiving a plurality of audio signals representative of spoken characters, the plurality of spoken characters specifying a string; and, through the audio-only interface, providing audible feedback in between each received spoken character. Additionally, the method can include the steps of: through the audio-only interface, audibly playing back each spoken character; accepting a voice selection of one of the played back characters, the selection denoting a disputed character; identifying a replacement character; and, replacing the disputed character with the identified replacement character in the specified string.
