Project description:
"We are looking for an experienced JavaScript developer to build an interactive voice widget for our website. This widget will function similarly to voice assistants like those from ElevenLabs, with a focus on seamless interaction between audio playback and user speech.

The core functionality involves a two-step process:
• Playback: The widget will first play a pre-generated greeting audio message to the user.
• Recording: Immediately after or during the playback, it must listen for the user's voice response.

Key Requirements:
• The successful candidate must develop a solution that handles the following:
• Audio Playback: Smooth playback of an initial greeting message from an audio URL.
• Overlap/Interruption Handling: The widget must be able to stop the greeting playback instantly when the user starts speaking (voice activity is detected). This is a critical feature.
• Smart Voice Recording: Initiate recording as soon as the user begins their query.
• Dynamic Recording End: The recording should not have a fixed duration. Instead, it must automatically stop when the system detects 3 seconds of continuous silence after the user's speech. This silence threshold should be easily configurable.
• API Integration: Once the recording is complete, the audio file (preferably in a format like WAV or MP3) must be sent to our backend API server via a POST request." (client-provided description)
