We hired two more voice-over professionals (male and female voices) to expand our database with audio recordings of American English words.
So far only the first batch of 2,000 words was released in our English phonetic translator. Eventually we will use these audios in our online American English pronunciation trainer as well.
We carefully proofread the IPA phonetic transcription of each and every word. This way when you practice you can be sure that what you hear matches perfectly the transcription that you see.
