With its advanced features, the SIGNUM spelling engine provides its end users with a broad range of benefits that cannot be obtained from similar engines.

• A vocabulary of more than 5,000,000 words comprising local and technical terms, with a vast morphological capability.
• A suggestions engine built for Spanish phonetics that provides excellent suggestions for typographical and orthographical errors.
• Suggestion lists that are short, accurate and intelligent to address the user's spelling errors.
• Intelligent recognition and flagging of conflictive homophones and paronyms in Spanish; these are words of very similar pronunciation, but which are written differently and have different meanings. For example, "ingerir" and "injerir", "binario" and "vinario".
• Appropriate handling of phrases that act as words. Three cases are considered: phrases that are to be written as two words, "a través"; phrases the meaning of which may change if they are written as two words or one word, "apropósito" and "a propósito", and those that have to be written as one single word, "autocrítica".
• Flagging of special words. For example, the program flags the word "indefensible" and recommends "indefendible" as a more educated term; or suggests "transporte" as a more traditional form than "trasporte". For a common error, such as the word "accesar", it suggests the proper term, which is "acceder". In the case of foreign words, for example, "cash" shows its Spanish equivalent, "en efectivo".
• Special features for OCR engines.
• Wide range of user options, so that revision may be more permissive or stricter, according to the user's spelling skill level.
