- presenting one or more transcribed words from the word lattice on a display screen of the mobile computing device;
- receiving, at the mobile computing device, a user selection of at least one of the presented transcribed words;
- in response to receiving the user selection of the transcribed word, presenting on the display screen one or more alternate words for the selected at least one word, from the word lattice;
- receiving, at the mobile computing device, a user selection of at least one of the alternate words; and
- in response to receiving the user selection of the at least one alternate word, replacing the selected transcribed word in the presented transcribed words with the selected alternate word.
2. The method of claim 1, further comprising:
- in response to receiving the user selection of the transcribed word, presenting a remove command on the display screen for the selected transcribed word;
- receiving, at the mobile computing device, a user selection of the remove command; and
- in response to receiving the user selection of the remove command, removing the selected transcribed word from the presented transcribed words.
3. The method of claim 2, further comprising:
- presenting at least one alternate phrase on the display screen from the word lattice for the presented transcribed words;
- receiving, at the mobile computing device, a user selection of the alternate phrase; and
- in response to receiving the user selection of the alternate phrase, replacing the presented transcribed words with the selected alternate phrase.
4. The method of claim 3, further comprising:
- in response to receiving the user selection of the alternate word or the remove command, automatically selecting at least one new alternate phrase from the word lattice based on the selected alternate word or the removed transcribed word; and
- replacing the presented alternate phrase with the new alternate phrase.
5. The method of claim 1, wherein receiving the user selection of the presented word and the user selection of the alternate word comprise receiving the user selection of the presented word and the user selection of the alternate word through a touchscreen interface of the mobile computing device.
6. The method of claim 1, wherein the word lattice comprises nodes corresponding to the transcribed words and the alternate words, edges between the nodes that identify possible paths through the word lattice, and each path has an associated probability of being correct.
7. The method of claim 6, further comprising identifying the alternate words for the selected transcribed word from one or more alternate paths between a beginning node and an ending node of the selected transcribed word in the word lattice.
8. The method of claim 6, further comprising identifying the alternate phrase for the presented transcribed words from at least one alternate path between a beginning node and an ending node of the presented transcribed words in the word lattice.
9. A computer program product, encoded on a computer-readable medium, operable to cause one or more processors to perform operations for correcting words in transcribed text, the operations comprising:
- receiving speech audio data from a microphone in a mobile computing device;
- sending the speech audio data from the mobile computing device to a transcription system;
- receiving, at the mobile computing device, a word lattice transcribed from the speech audio data by the transcription system;
- presenting one or more transcribed words from the word lattice on a display screen of the mobile computing device;
- receiving, at the mobile computing device, a user selection of at least one of the presented transcribed words;
- in response to receiving the user selection of the transcribed word, presenting one or more alternate words on the display screen from the word lattice for the selected transcribed word;
- receiving, at the mobile computing device, a user selection of at least one of the alternate words; and
- in response to receiving the user selection of the alternate word, replacing the selected transcribed word in the presented transcribed words with the selected alternate word.
10. The computer program product of claim 9, the operations further comprising:
- in response to receiving the user selection of the transcribed word, presenting a remove command on the display screen for the selected transcribed word;
- receiving, at the mobile computing device, a user selection of the remove command; and
- in response to receiving the user selection of the remove command, removing the selected transcribed word from the presented transcribed words.
11. The computer program product of claim 10, the operations further comprising:
- presenting at least one alternate phrase on the display screen from the word lattice for the presented transcribed words;
- receiving, at the mobile computing device, a user selection of the alternate phrase; and
- in response to receiving the user selection of the alternate phrase, replacing the presented transcribed words with the selected alternate phrase.
12. The computer program product of claim 11, the operations further comprising:
- in response to receiving the user selection of the alternate word or the remove command, automatically selecting at least one new alternate phrase from the word lattice based on the selected alternate word or the removed transcribed word; and
- replacing the presented alternate phrase with the new alternate phrase.
13. The computer program product of claim 9, wherein receiving the user selection of the presented word and the user selection of the alternate word comprise receiving the user selection of the presented word and the user selection of the alternate word through a touchscreen interface of the mobile computing device.
14. The computer program product of claim 9, wherein the word lattice comprises nodes corresponding to the transcribed words and the alternate words, edges between the nodes that identify possible paths through the word lattice, and each path has an associated probability of being correct.
15. The computer program product of claim 14, the operations further comprising identifying the alternate words for the selected transcribed word from one or more alternate paths between a beginning node and an ending node of the selected transcribed word in the word lattice.
16. The computer program product of claim 14, the operations further comprising identifying the alternate phrase for the presented transcribed words from at least one alternate path between a beginning node and an ending node of the presented transcribed words in the word lattice.
17. A computer-implemented system for correcting words in transcribed text, the system comprising:
- a transcription system operable to receive speech audio data and in response transcribe the speech audio data into a word lattice; and
- a mobile computing device comprising:
- a microphone operable to receive speech audio and generate the speech audio data,
- a network interface operable to send the speech audio data to the transcription system and in response receive the word lattice from the transcription system,
- a display screen operable to present one or more transcribed words from the word lattice,
- a user interface operable to receive a user selection of at least one of the transcribed words,
- one or more processors and a memory storing instructions that when executed by the processors perform operations to present one or more alternate words on the display screen from the word lattice for the selected transcribed word, receive a user selection of at least one of the alternate words, and replace the selected transcribed word in the presented transcribed words with the selected alternate word.
