Electronic Voice Phenomena (EVP)
Are these the voices of the dead?
The recordings here represent direct responses to questions, most are Class A (very clear) and Class B (mostly audible).  The recordings were taken during paranormal investigations at the Philip Williams House, Winchester, Virginia, in 2017 & 2018.

Who is Alice? Uncertain, but the voice repeats the name quite clearly in a whispered voice.

In response to asking questions and wrapping up the evening, quite polite. Thank you at the 18 second mark.

Soft voice saying "Hi" as we made our way up to the third floor. Listen at 3 seconds.

 A high-pitchy almost clown-like or childish voice in response to our introducing ourselves. Listen carefully at the 1-2 second mark.

In response to inquiring about a Civil War Soldier's  presence-significant as one defining battle took place 20 miles from this Winchester location. Faint at the very beginning.

Is this a reference to Mary Williams? She died in the house April 2, 1878. Listen at 5 seconds.
