Explanation
No. The 1927 version of The Jazz Singer was a part-talking film, combining silent-film storytelling with recorded musical performances and limited spoken dialogue.
The American Film Institute's catalogue classifies its physical format as silent with sound sequences. Independently, the British Film Institute describes it as largely silent, with musical sequences and brief passages of speech.
The distinction is between containing synchronized speech and being an all-talking production. The Jazz Singer helped accelerate cinema's transition to sound, but that historical impact does not make it a film with spoken dialogue throughout.
Key takeaway
The Jazz Singer helped popularize talking pictures while still retaining much of the silent-film format.
