From Bulbapedia, the community-driven Pokémon encyclopedia.
Chatter (Japanese: おしゃべり Chatter) is a damage-dealing Flying-type move introduced in Generation IV. It is the signature move of Chatot.
Chatter inflicts damage and may confuse the target. This move allows the player's voice to be recorded using the Nintendo DS's microphone, which will play back during the attack and as Chatot's cry.
The chance of confusing the foe is determined by the volume of this recording. Generally, the higher the volume of the recording is, the higher the chance of confusion. The recording is stored as a 1000-byte structure within the game as a 4-bit PCM (pulse code modulation) recording. When a sound is recorded, 1984 8-bit samples of microphone input are taken at roughly 2000 samples per second. 16 zero byes are appended onto the end of this recording to create a 2000 byte 8-bit PCM recording, which is then downsized to a 4-bit PCM recording via a translation table:
|| -127 - -112
|| -111 - -96
|| -95 - -80
|| -79 - -64
|| -63 - -48
|| -47 - -32
|| -31 - -16
|| -15 - 15
|| 16 - 31
|| 32 - 47
|| 48 - 63
|| 64 - 79
|| 80 - 95
|| 96 - 111
To pack two 4-bit samples into a byte, the first sample takes up the lower four bits and the second sample takes up the upper 4 bits. Now, depending on the value of the 16th byte in the 1000-byte 4-bit PCM recording (corresponding to the 31st and 32nd samples from the original), the chance of confusion is as follows:
|| Confusion odds
| -31 or less
| -30 to 29
| 30 or more
The volume level roughly corresponding to the specific values are given in the table. When Chatter is used by wild and Trainer-owned Chatot, or Chatot who have not had a voice recorded for them, the sound used is Chatot's regular cry, and the odds of confusion is set to 1%. Note that since the sample is near the beginning of the recording, it is not necessary to maintain a high volume throughout the recording.
The odds of confusion is not affected by Serene Grace, but is affected by Shield Dust.
Chatter can hit non-adjacent opponents in Triple Battles.
Generation V games record 8000 8-bit samples at 8000 samples per second for its recordings, and converts every fourth sample taken from these, starting with the first sample, to the 1000-byte 4-bit PCM recording in the same manner as that of Generation IV. However, instead of one byte determining the confusion odds, the exclusive or of three bytes, the 100th, 500th, and 700th bytes (corresponding to the 397th, 401st, 1997th, 2001st, 2797th and 2801st samples of the original recording), are taken. The odds of confusion are calculated as follows:
|| Confusion odds
| 99 or less
| 100 to 149
| 150 or more
Thus, it is necessary to maintain medium or high volume in roughly the first quarter-second for the maximum odds of confusion. When Chatter is used by wild and Trainer-owned Chatot, or Chatot who have not had a voice recorded for them, the sound used is Chatot's regular cry, and the odds of confusion is set to 0%. The confusion odds are affected by Shield Dust, Serene Grace, Sheer Force, and the combined effect of Water Pledge and Fire Pledge.

In other generations
- Chatter is the one of only two moves that cannot be Sketched, presumably because as a field move, if used by a Pokémon other than Chatot, it does not temporarily change the battle cry of the respective Pokémon to the recorded version even if audio is recorded. This is because recording audio via Chatter activates a Pokémon's alternative cry, where Chatot's alternative cry exclusively depends on what was recorded when the Chatter field move is used.
- This makes it one of the only two true signature moves, the other one being Sketch itself. The only other moves which can't be Sketched are Struggle and shadow moves which cannot be learned naturally.
- When a person's voice is recorded for the move, the noise will always be distorted, possibly a failsafe to prevent obscene language from being emitted by the game.
- After using Chatter outside of battle, the Pokémon's cry will be temporarily changed. In the profile, the cry will be what was recorded. Moves such as Growl and Howl will change as well due to its cry being changed. This will be reset when the Pokémon is deposited into the PC.
- Chatot is banned from the Pokémon Global Battle Union because of Chatter.
