Fact · Dictation on phones and tablets
25times
In 2019, Google's older server search graph was no more than 25 times the size of the on-device Gboard speech recognizer.
Checked against its source on October 17, 2026
- How it is calculated
- 2,000 MB divided by 80 MB = 25. The source gives the server graph as almost 2 GB, so 2,000 MB is an upper bound and the ratio is at most 25.
- What it does not show
- This compares the size of two different 2019 models, not their accuracy or the words each covers.
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.
