Fact · Dictation on phones and tablets
25times larger
Google's pre-2019 server speech graph, almost 2 GB, was about 25 times the size of the 80 MB on-device Gboard model it moved to the phone.
Checked against its source on October 17, 2026
- How it is calculated
- 2 GB = 2,000 MB; 2,000 / 80 = 25 (approximate, because the source says almost 2 GB)
Calculated from
- Google said its traditional server-side recognizer used a search graph of almost 2 GB, too large for a phone, which is why it needed a connection.
- In 2019 Google moved Gboard voice typing onto the phone with an 80 MB speech recognizer that works even when the phone is offline, first on Pixel phones in American English.
