Speech Recognition Development

What We Can Do For Your Speech Application

MatrixHCI can conduct a careful analysis of your requirements and help you determine the best way to implement a successful speech system solution that will meet your current and future needs.  MatrixHCI can evaluate your implementation environment and help identify areas of challenge in acoustics, grammar, recognition, and system and human interface points.

MatrixHCI can provide your firm with a complete system recommendation and an architectural plan for developing just the right speech recognition system to meet your needs.  Once approved, your plan will be used to develop your speech application using proven software engineering methods.  This will ensure that your project is delivered on time, within budget, and in a way that fully meets your requirements.

Automatic Speech Recognition (ASR) Development Services

First impressions are priceless, especially when it comes to speech recognition.  When used successfully, it can be of great benefit to both you and your customer; however, make one wrong turn and your company’s image and the success of your speech implementation is out the window.

“I’m sorry, I didn’t get that.”  Such a response tarnishes your company’s image.  Like it or not, your speech recognition system is an outward reflection of your organization and that’s why it’s important to plan your speech presence carefully.  Successful businesses turn to MatrixHCI when it comes to speech recognition development and consulting needs.

MatrixHCI’s team of voice recognition experts offers a rich set of talent and experience in the speech recognition field, and has developed successful speech applications that perform under the most demanding acoustical and speech environments.  Using proprietary development and acoustic training techniques, MatrixHCI has outpaced leading voice recognition products in tough environments, such as real-time air traffic control.

Your success is our top priority.  MatrixHCI’s advanced speech development capabilities are built around formal software engineering principles and methodologies.  You can be assured that your project is developed and delivered in a way that successfully meets your technical and financial objectives.

Whether it’s a brand new speech application or a refresh of an existing implementation, MatrixHCI offers years of experience developing state-of-the-art next-generation applications.

MatrixHCI offers a wide variety of development services that can be customized to meet your company’s specific needs.  Our menu of services includes:

Developmental Considerations

Proper ASR requirements and expert speech engineers are crucial for a successful enterprise speech application.  Speech recognition depends on a series of cumulative operations whose pivotal interrelations are not well documented or understood by traditional software developers.  Speech is further prone by the inconsistent nature of audio inputs. These factors equate to a brittle technology that’s easily “broken” making speech systems a high risk for failure when not well planned, designed, and trained.

Some of the factors that can trigger a failed system response are: background noise as a speaker talks, a word or sentence spoken too quickly, a mismatch in acoustic properties, a poorly developed acoustic model, or an inflexible grammar file that cannot handle out-of-vocabulary (OOV) inputs.

Negative results from speech recognition systems can leave customers with bad experiences.  At minimum, these compromise any competitive advantage, but in mission-critical environments these inadvertent system errors can have catastrophic or even life-threatening results.

Below is a listing of critical topics that must be properly addressed when developing and designing speech applications:


Acoustic Conditioning and Filtering and Normalization
Acoustic Segmentation
Pre-Recognition Acoustic Packaging

Corpus Data Collection and Acquisition
Recognition Encoding
Acoustic Model Training
Encoder Tuning

Optimization of Engine or Parameters
Intelligent Error Avoidance or Recovery
Protocols to Integrate with Outside Programs
