Avaz has a prediction feature called Phonetic match - this predicts words based on their phonetic sound. E.g. if you type ‘fone’ Avaz predicts ‘phone’. Tap Settings > Prediction and turn ‘Phonetic match’ to ON to enable this.
Example 1 : Note how the word phone is prompted in the prediction bar, when you type the word fone.
Example 2 - Note how the word Spaghetti is prompted in the prediction bar when the letters 'spug' are typed.
