The Vietnamese language belongs to the Mon-Khmer branch of Austroasiatic languages​​. It is spoken in Vietnam by 98 million people, 85% of whom are from Kinh Kinh and 15% from ethnic minorities using Vietnamese as their primary language. It is also the language spoken by Vietnamese minorities in neighbouring countries: China, Laos, Cambodia and Thailand, where many Vietnamese people live. It is a monosyllabic language which has a system of six tones. The assimilation of tones, as well as comprehending spoken Vietnamese, is the biggest challenge of learning the language. This course devotes an important chapter  to this in the introduction, to which the audio recording is an essential addition. The book is divided into three parts with a total of sixty lessons in classical structured text, vocabulary and grammar. A Vietnamese-French lexicon of 96 pages can be found at the end of the volume. Audio recordings that go along with the first part of this book can be downloaded for free by clicking here. About 50 minutes of listening.
