Sonnet is a multilingual spell checker program in KDE Frameworks 5 and KDE Software Compilation 4. Sonnet replaced kspell2 that was created for KDE3. The two main goals for Sonnet's development were a simpler API, wider language support and performance. Notable improvements in Sonnet over kspell2 are:
- In automatic language detection, a language can be identified with as little as 20 characters of text. Even multiple languages in the same document can be detected and spell checked correctly
- Better performance
- Improvements in spell checking languages like Thai and Japanese
- A simpler design - kspell2 consisted of 7 components and a complicated API. Sonnet is a single component and aims to provide a simpler API
- The user can select a primary and backup dictionary, an example given was a doctor who frequently uses terms from a medical dictionary. Words that would not appear in a regular dictionary would be corrected by the backup dictionary that contains medical terms.
