This page is for download of a SAPI4 speech client for Brainhat and Pandorabots servers.
The client works with speech recognition (SR) engines and text to speech (TTS)
engines complying with the Microsoft SAPI4 specification, including
Dragon NaturallySpeaking, IBM ViaVoice and Microsoft. You will need
the MS SAPI4 API layer, available from Microsoft at
. Choose the "suite" if you have no alternate speech output (TTS).
Don't choose SAPI 5--it is not compliant with SAPI 4.
The client can also operate as a text-only interface; speech
components are not required.
Use "Preferences" to select a server and/or speech interface:

Speech recognition can be improved slightly by supplying hints to the SR
engine. Brainhat servers supply these hints from the context of the
conversation, or from a hand-crafted set of statements residing on the
server. When using this client with a bot, you can improve the SR
rate by populating the file hints.txt with statements you expect to
- Speech Recognition (SR):
Available SAPI4 compliant speech engines will appear within the
"Speech Recognition" box. Choosing an engine will cause a
list of known users to be displayed in the "User" box below.
Select a combination of engine plus user. If no users are
displayed, please see speaker enrollment tools that come with
your speech engine; speakers must be known to the engine in
Text to Speech (TTS):

You may edit existing connections or create new ones. Click
the "New" button to create a new connection. Choose a name
for the connection in the "Name" box. The "Address" box must
contain a domain name or IP address. The "Server Type" can
be one of "brainhat" or "pandora". The "ID" field is ignored

create an account and publish a bot. Your bot will have a botID
associated with it. To find the bot ID, go to the "Botmaster Control"
page and mouse-over "Run Last Published" for the bot you wish to
connect to. The URL will contain the bot ID that you need for the
"Preferences" menu discussed above.
Brainhat is a platform that represents knowledge, runs inferences
and creates output. It can be a good companion for a bot because
it can be goal oriented; Brainhat can help drive a conversation
toward a given task. Brainhat can also help with speech recognition
because it continually feeds contextual hints to the speech recognizer.
You may run a Brainhat server alone or in conjunction with an AIML
bot on the Pandorabots site. When running solo, a Brainhat server
will converse from the domain(s) available to it. When Brainhat
runs in conjunction with a Pandorabots AIML bot, it will share
everything it hears with the bot. Responses from the bot and
Brainhat will be combined.
