You can improve the rate of words recognized by the engine by creating a Vocabulary containing the pronunciation of difficult words.
To create a new dictionary or edit an existing one, go to the Vocabularies tab via ACCOUNT . All your Vocabularies are listed here. To add to an existing dictionary, click on "Edit" to the right of the Vocabulary. If you want to create a new Vocabulary, click on "Create a new vocabulary" at the bottom.
A vocabulary consists of individual words, sentences or phrases and the way they are normally pronounced. In the left column you write the correct spelling of the word/phrase, which is then also displayed as a subtitle (this is the most important step). In the right-hand column you can optionally enter the pronunciation. This is either described using the conventional alphabet (e.g.: F.B.I. --> "Eff bi ai") or it is described using the International Phonetic Alphabet(IPA) or phonetic speech (e.g.: F.B.I. --> "ɛ f b i aɪ").
The entries can now either be imported into the dictionary collectively as an existing .csv or .txt file or they can be added individually as entries. Once you have added all the entries, click on "Create vocabulary" (or "Update vocabulary" if you are editing an existing one).
To now use the Vocabulary in your SPEECH session, you have to select it under Input source after creating the session.
