<h1>Phonetic Matching Functions</h1>
  <p>These functions provide standard algorithms for phonetic fuzzy matching on strings. They each accept a string as a
  parameter and return a canonical string representing the pronunciation of the input. The specific meaning of the
  resulting string depends on the algorithm. These functions support ASCII strings only; they will throw an error if a
  string containing non-ASCII characters is provided. These functions are provided by the <a moz-do-not-send="true"
  href="https://github.com/nalgeon/sqlean">sqlean "fuzzy"</a> extension which is built into SQL Notebook.<br></p>
