The human factor in engineering voice applications
The field of human factors has two major goals: to improve the effectiveness or productivity of people (for example, performance) and to enhance human values (for example, improve comfort, safety, or satisfaction).
Human factors practices are variable and can be called by just about any name. Often, human factors experts emphasize their particular method, because it is the method they use that produces measurable outcomes like ease of use, usability, or positive user experience.
Basically, anytime something comes up related to how people will use a technology, that is the appropriate time for human factors consultation. Human factors experts should be consulted to provide user requirements, use cases, design user interfaces, and user feedback on usability or satisfaction. They are more effective in the earliest stages of development; at this point, their work is proactive because the system has not yet been built. At the same time, this stage is challenging because everyone on the team needs to trust the human factors recommendations.
In reality, it's much more common for a development team to realize they need usability testing toward the end of development. This approach is reactive and does not allow the human factors professional to design a system around the user. This is a reactive approach and can lead to conflicts within the development team and usability problems in the speech interface.
