Access and layout of the Lab

The PhonLab is located in 50-52 Dwinelle on the classroom side of Level C, along with the offices across the hall (49-57 Dwinelle).

  • Room 50 is the office space for grad students and visitors. The Lab printer is also here.
  • Room 51 and Room 53 have small sound booths for running perception experiments.
  • Room 52 has a large sound booth and is primarily used for speech production experiments.
  • Room 55 contains the Lab library and sometimes houses visitors.
  • Room 57 is for sociophonetic research. It is called SpARCL (Sociophonetic Area for Recording Conversational Language).

Graduate students and visitors who need unrestricted access to the Lab should contact Keith Johnson or Susan Lin for permission to obtain a key, and Ronald Sprouse for an alarm code and instruction on how to use it.

Lab security

The PhonLab is located in the public portion of Dwinelle Hall. This part of the building is open on evenings and weekends, and is usually bustling with people. It is important to keep in mind that there are people out there who would be very happy to take our computers off our hands. Arm the alarm system when the space is not in use!

Room 50

The offices (50 and 55 Dwinelle, and 556 Evans) are intended to be used as work spaces, for reading, writing, studying, analyzing data, etc. Conversation, whether professional or personal, is inevitable, but please respect your colleagues’ need for quiet, and keep your conversations brief and at a reasonable volume.

Offices should not be used for

  • GSI office hours -- you should have been assigned a GSI office for those purposes (Evans may be used for GSI office hours)
  • Research meetings
  • Behavioral research

Room 51

There are two soundbooths in this room that are used almost exclusively for speech perception experiments. Each booth is equipped with a Mintbox computer, a PST response box, and a pair of headphones.

To use this room you should reserve time on the lab calendar. See the Lab scheduling page for instructions.

The operating system on these little machines is the same as on the Berkeley Phonetics Machine, so when you develop software on the BPM using OpenSesame, for example, it should work with no changes on these machines.

Room 52

This is the Articulatory Phonetics Lab. The equipment in this room includes:

  • a double-walled whisper-room soundbooth (100 square feet)
  • a Ultrasonix ultrasound machine
  • an aerodynamics rig (Biopac)
  • static palatography camera and supplies


Room 53

There is one soundbooth in this room that is used for speech perception and production. It is equipped with a Windows computer, an AKG C3000 microphone, a response box, and a pair of headphones.

Outside of the soundbooth, there is a Windows computer on a desk, and a smaller desk by the side.

To use this room you should reserve time on the lab calendar. See the Lab scheduling page for instructions.


Room 55

This room is partially a library of working papers and reprints, and also has desk space for two researchers.

Room 57

Is designed to record naturalistic conversation between multiple speakers or speakers and researchers. The room is arranged to look like a living room, with furniture to accommodate up to four subjects. It is equipped with two lapel mics and one boom microphone, as well as a desktop Mac with OSX - El Capitan.

To use this room you should reserve time on the lab calendar. See the Lab scheduling page for instructions.

When using this room, it is recommended to place the "Recording in Progress" sandwich board outside in the C-Level hallway, as SpARCL is located right next to classrooms and bathrooms, and it gets very noisy.
