The Jazz Singer

What were some technological issues that came up when it was first being implemented? What was significance of "The Jazz Singer" in film sound history?

In order to perfectly synchronize the audio with the visual, a Kinetophone was first invented. However, this device had very weak amplification abilities. Thus, the sound was only able to be heard one person at a time. Some versions of audio recording devices using disks were invented later, one of them being the Phonoscene. However, this method had poor amplification abilities and lost sync quickly. The Tri Ergon process was then invented, allowing audio to be recorded directly on the film. The Jazz Singer only included a couple clips with audio. However, these couple clips introduced Hollywood to the world of cinema with sound. Later on, most if not all films included synchronized audio.
