We present a requirements engineering environment which provides techniques and tools to improve communication in Requirements Engineering activities. First, a technique based on requirements ontologies is proposed to allow customers to describe their needs. This technique is supported by a tool. This tool provides analysts with structured descriptions of the customers' needs that facilitate analysts to understand the problem to be solved. Next, both a model-to-text transformation and a model-to-model transformation are introduced to automatically obtain a textual requirements specification and a taskbased requirements model respectively. The textual specification facilitates customers to validate requirements. The task-based requirements model facilitates programmers to interpret the requirements specification.
