This document contains information for WebSphere Voice Server version 5.1.3 fix pack 1, hereafter referred to as version 5.1.3.1. It also contains links to the latest product information.
This readme contains the following information:
WebSphere Voice Server Version 5.1.3.1 includes improved acoustic models for German and UK English.
Version 5.1.3.1 also provides fixes for the following problems:
WebSphere Voice Server Java core dumps when stack overflow happens because of deep recursive calls in the Grammar Compiler, such as when the Grammar Compiler tries to compile a grammar with a rule with very long sequential tokens. A protection mechanism has been added to the Grammar Compiler to catch the stack overflow. It reports a warning message (CWVGC2041E) so that a Java core dump will not happen. If a user sees the warning message, they can reduce the rule length to avoid the core dump. Since a lengthy rule is not realistic in a real application, the long rule might be caused by typo or badly written grammars.
This fix pack fixes the problem that occurs when long grammar URIs are used in an application. URIs that are greater than 257 characters in length can corrupt the grammar cache. This fix pack allows long grammar URIs to be used without corrupting the cache.
The "MapViewofFile failed(8)" error is logged in the SystemOut.log file when compiling grammars repeatedly with many channels. A memory leak in the Grammar Compiler causes the not-enough-memory error.
WebSphere Voice Server 5.1.3 Grammar Compiler had memory leaks using certain grammars.
A problem occurs when using external DTMF grammars that expire at the same time as they are unloaded by the recognition engine.
SRGS semantic interpretation results may erroneously include references to objects that contain circular references. In this case, the circular reference would cause the NLSML generation to recurse indefinitely. This fix pack resolves this erroneous SISR by limiting the stack depth to 20 properties. A semantic result cannot contain a tree of properties deeper than 20 nodes.
WebSphere Voice Server might not detect a simple DTMF tone but instead report a "no input timeout". This situation has been corrected.
Some IVRs would throw an error when receiving 402 to a MRCP RECOGNITION-START-TIMERS received after speech recognition completed. WebSphere Voice Server no longer sends a 402 in this situation.
ASR Engine failovers will occur under a load with Windows 2003 SP1 applied.
From some IVRs, when TTS receives text with delimiters inserted, TTS might concatenate words together.
Consecutive tags were not adding up and only the first value was being honored. With this fix pack, the breaks are summed up and the appropriate pause is generated by the TTS system.
When specifying large numbers through a sayas tag, TTS incorrectly speaks the number.
The size of a phrase could affect whether it was successfully stored in the cache. This fix pack ensures all phrases are cached regardless of size.
With this fix pack, WebSphere Voice Server supports new fifth generation TTS voices that do not need to be selected during the installation.
This fix pack resolves the problem where voicetest does not correctly read the MRCP header cache-control:max-age from the user.
The isolated period punctuation led to a problem in which the English engine was trying to add a pause but was not sure where to put it since isolated punctuations are typically read out.
When multiple MRCP clients use the same grammar and lexicon file at the same time, the grammar compiler may not respond.
