Voice in Second Life uses [http://www.vivox.com/ Vivox] technology that is based on RTP (using the [http://www.linphone.org/index.php/eng/code_review/ortp oRTP] library), SIP (using the amsip library from [http://www.antisip.com/ Antisip]), [http://www.openal.org/ OpenAL], [http://tinyxpath.sourceforge.net/ TinyXPath], [http://www.openssl.org/ OpenSSL], and [http://curl.haxx.se/ libcurl] for the transmission of voice data. The positional 3D audio is achieved with technology from [http://www.dw.com/about.php DiamondWare]. These technologies are contained in external daemon software that is started and stopped by the Second Life client.
See [[User:Torley Linden|Torley Linden's]] page on [[Voice recording]]


The SecondLife viewer handles configuration, control, and display functions, but the voice streams (from the microphone and from the Vivox voice server) do not enter the viewer.  Unfortunately the source code for the external SLVoice daemon is not available due to contractual obligations between Linden Labs and Vivox.
==LipSync==


The executables can be found in the Program Files\SecondLife directory of the runtime and in the linden\indra\newview\vivox-runtime\(platform) directory of the source distribution.
See the [[LipSync]] page for information on lip sync for voice chat.

===SLVoice===
----
 
SLVoice is started from the viewer in SLVoiceClient::stateMachine() using:
 
:'''SLVoice.exe -p tcp -h -c -ll <''VivoxDebugLevel, default -1''>'''
 
usage: '''SLVoice [''flags'']'''
 
valid flags are:
:    [-ll <log-level>] 0-5, or -1 for no logging
:    [-lf <log-folder>]
:    [-lp <log-file prefix>]
:    [-ls <log-file suffix>]
:    [-p tcp]
:    [-i <address>] application sends requests to this address
:    [-o <address>] according to the executable, the gateway sends responses and events to this address, but according to the official documentation, the gateway both sends and receives to/from this address.  Please update this if you determine which is correct.
:    [-vo] vivox only functionality
:    [-ov] (undocumented and unused)
:    [-c] cleanup orphaned SLVoice processes.  If this is the only argument to SLVoice, then it cleans up and exits; if there are other arguments, it cleans up any old instances and launches a new one.
:    [-h]  hide the window associated with SLVoice.  On MS Windows, this appears to be the default, because there is no window whether this parameter is set ot not.
:    [-r]  (undocumented and unused)
 
SLVoice.exe was called  vivox-gw.exe in the beta release, so you may still see some references to the old name.
 
====IP Address====
The SecondLife viewer uses IP address 127.0.0.1 (localhost), port 44124 to communicate with SLVoice, the voice client gateway.
 
It is possible to connect to a client gateway running on another host.  This is useful for testing.  According to comments in the source code: to do this, launch the gateway on a nearby host,
 
:  '''SLVoice.exe -p tcp -i 0.0.0.0:44124'''
 
and modify the code in SLVoiceClient::stateMachine() to set the host IP address, '''mDaemonHost'''.
 
====Logging====
 
The logging for SLVoice is controlled by a viewer variable, VivoxDebugLevel.  You can set it directly in your '''Documents and Settings\<user>\Application Data\SecondLife\user_settings\settings.xml''' file
 
:: <nowiki><!</nowiki>--Logging level to use when launching the vivox daemon-->
:: <VivoxDebugLevel value="5 -lf myDirectory -lp myPrefix -ls .txt"/>
 
or you can set it from the viewer.  To set it from the viewer, you have to enable the Client menu if you haven't already using Ctrl-Alt-D (not to be confused with Ctrl-Alt-Delete).  Then select
 
: Client -> Debug Settings
 
to get the Debug Settings window.  In the selection box, hit the triangle to bring up the list of debug variables and select VivoxDebugLevel.  In the text entry box, you'll see the current value.  Above it is the description, "Logging level to use when launching the Vivox daemon."  You can set the level as you like.  If you want the output to go somewhere other than the default location, you can enter it in the box as well, for example,
 
:: '''5 -lf myDirectory -lp myPrefix -ls .txt'''
 
If <log-folder> is a relative path, it is relative to the directory that SecondLife is running in, ususally '''C:\Program Files\SecondLife'''
 
The default folder is '''c:/Documents and Settings/<user>/Local Settings/Application Data/Vivox/logs'''.  The default prefix is '''SLVoice''' and the default suffix is '''.txt'''.
 
The log file is named <nowiki><log-file prefix>-<yyyy>-<mm>-<dd><log-file suffix></nowiki>
 
The default on September 3, 2007, for example, would be: SLVoice-2007-09-03.txt
 
The <log-level> must be at least 2 to see INFO messages and 4 to see TRACE messages.
 
 
Whenever log level is other than "-1", there is also a log file written to '''LL_PATH_LOGS''', which is usually set to '''c:/Documents and Settings/<user>/Application Data/SecondLife/logs''',
with the <log-file prefix> "Connector," that contains log information for the Connector.  This logging comes from vivoxsdk.dll which is used by SLVoice.exe.  The content does not depend on the log level for SLVoice; the Connector.Create.1 request hardcodes the Connector log level at 10.
 
 
*There is apparently no Response sent to the viewer for [[#Session.Set3DPosition.1|Session.Set3DPosition.1]]
*SLVoice does not log [[#ParticipantPropertiesEvent|ParticipantPropertiesEvent]]
*SLVoice does not log [[#Account.Logout.1|Account.Logout.1]]
*SLVoice may not log the Response to [[#Connector.InitiateShutdown.1|Connector.InitiateShutdown.1]] but when it does it tends to spew tens of thousands (about ten per millisecond) of messages to the log.
::17:11:38.988, 0x00001414, INFO , disconnectHandler Client Connection Closed - shutting down
::17:11:38.988, 0x00001414, INFO , shutdownGateway Terminating Gateway Process
 
 
SLVoice logs commands with added default values for fields not sent by the viewer, for example,
 
:for [[#Account.Login.1|Account.Login.1]] the log includes fields
::<AccountURI />
::<ParticipantPropertyFrequency>10</ParticipantPropertyFrequency>
::<EnableBuddiesAndPresence>false</EnableBuddiesAndPresence>
 
:for [[#Connector.Create.1|Connector.Create.1]]
::<AttemptStun>AttemptStunUnspecified</AttemptStun>
::<MinimumPort>22860</MinimumPort>
::<MaximumPort>22892</MaximumPort>
 
:for [[#Session.Create.1|Session.Create.1]]
::<Password />
::<JoinAudio>true</JoinAudio>
::<JoinText>false</JoinText>
::<PasswordHashAlgorithm>ClearText</PasswordHashAlgorithm>
 
:for [[#Session.Set3DPosition.1|Session.Set3DPosition.1]]
::<OrientationType>legacy</OrientationType>

==Technical==


Voice in Second Life uses [http://www.vivox.com/ Vivox] technology that is based on RTP (using the [http://www.linphone.org/index.php/eng/code_review/ortp oRTP] library), SIP (using the amsip library from [http://www.antisip.com/ Antisip]), [http://www.openal.org/ OpenAL], [http://tinyxpath.sourceforge.net/ TinyXPath], [http://www.openssl.org/ OpenSSL], and [http://curl.haxx.se/ libcurl] for the transmission of voice data. The positional 3D audio is achieved with technology from [http://www.dw.com/about.php DiamondWare]. These technologies are contained in external daemon software that is started and stopped by the Second Life client.


For more details, see the [[Voice/Technical]] page, or have a look at the official [http://jira.secondlife.com/secure/attachment/12026/Vivox-SLVoice-SDK-2007-09-20.pdf ViVox documentation on the JIRA].

Voice is the ability to speak and hear other Residents in Second Life. See Voice Mentors: Getting Started with Voice for some introductory information.

Frequently Asked Questions

There's an exhaustive Voice FAQ which provides answers to many questions about the new voice feature.

Groups

The Voice Mentors group and Voice in SL: A Community Forum are advocacy and help groups for users having problems adjusting to the new system.

Settings

You can set your preferences directly in your Documents and Settings\<user>\Application Data\SecondLife\user_settings\settings.xml file, or you can set them from the viewer.

Some settings can be made through the UI panels, but all can be set from the advanced menu.

If you haven't already done so, you enable the Advanced menu using

  • PC - Ctrl-Alt-D
  • Mac - Ctrl-⌥ Alt-D
KBnote.png Note: In some cases, there may be a shortcut conflict with another application. In which case, hold down Ctrl-Alt-⇧ Shift-D.

(not to be confused with Ctrl-Alt-Del).

Then select:

Advanced -> Debug Settings

Note: If you are on Mac OS X, this key combination can possibly hide your Dock. If this happens, click the Apple icon (upper left) then click Dock, then click Turn Hiding Off.


to get the Debug Settings window. In the selection box, hit the triangle to bring up the list of debug variables and select the setting that you wish to change.
