Troubleshooting General Recognition Problems
The first step in troubleshooting is to determine which type of speech recognition is being used, BlueStreak or Pick Up & Go. There are some troubleshooting items unique to the type of speech recognition used while some troubleshooting tips affect both types.
If a worker or group of workers report problems with their recognition, you should first determine if the problem is with the recognition performance or with something else, such as expectations. To evaluate performance at a site, you can:
- Interview a worker
- Follow a worker around with a listening device while he or she is performing a task
Before proceeding too far down the troubleshooting path, check that the site is using the newest firmware and that the application is configured to work with Honeywell Adaptive Speech Recognition.
The causes of most legitimate recognition problems fall into four categories:
Issues stemming from these causes and possible resolutions are explained further in the following subsections, which are grouped according to their symptoms.
If a worker regularly experiences any type of recognition problem, try the following to rule out a hardware issue:
- Check the headset connector to the device to make sure it is properly connected.
- Make sure the headset cable and connector are not binding on the worker's clothing so that the connector is not occasionally pulled out while the operator moves.
- Check the electrical contacts on the connector for wear. If you suspect bad contacts, listen to the headset while wiggling the connector. Static may indicate a bad connection.
- Instruct the worker to try a different headset and see if the problems go away. Try the suspected bad headset on another device to determine if the cause is the headset or the device.
- If the worker is having trouble with multi-word phrase, such as "Review Contents", "Skip slot", and "Take a break", the worker may have paused too long between words during template training, causing part of what he spoke to get cut off and excluded from the template. Review the best practices for training with the operator. In particular, have the operator retrain the words without pausing between the words.
If the worker is in a freezer environment:
- Squeeze the windscreen regularly to break up ice that may have formed on it.
- Replace the worker's windscreen with a fresh one whenever it becomes frozen.
- Wring out the windscreen when it becomes wet or frozen.
- Allow the headset to thaw and dry, if it was frozen or wet, and have the worker use another headset.
- Instruct the worker to try a different headset and see if the problems go away. Try the suspected bad headset on another device to determine if the cause is the headset or the device.
