Creates a new Soniox STT dictionary for the partner. Terms are normalized server-side: whitespace is trimmed, empty/whitespace-only entries are dropped, non-string entries are silently skipped, and the dedupe is case-insensitive but preserves first-occurrence casing. A blank description is stored as null. Dictionary names must be unique per partner.
