Investing in a speech analytics solution is a big decision for any company as it is generally linked to considerable expenses. Nevertheless, more and more enterprises today embark on this opportunity. As practice shows, they can expect the return on investment in just three to twelve months.

In one of our recent blogs, we have already retold you about the numerous benefits the speech analytics solutions bring to organizations. Among them are the exceptional customer experience, reduced expenses, increased revenue, and minimized customer churn. In practical terms, the solution makes possible to reduce time spent on speech transcription and quicker perform a comprehensive analysis of the mined data.

If your organization is also planning on getting a speech-to-text transcription and analytics tool for your front office, consider conducting a thorough research prior to making a concrete purchase. This will give you an opportunity to identify the right solution that is ideal for achieving your business goals. Not to get lost in the sheer number of options available in the market keep in mind 5 main questions while assessing the quality of the offered speech analytics product.

1. Does the Solution Offer the Real-Time Speech Recognition?

Real-time processing of speech is an important feature of any speech-to-text transcription and analytics service. Having recognized predefined keywords in real-time conversations, the service displays the relevant information on the agent’s desk, successfully guiding him through an uneasy or important talk. Due to the use of scripts and knowledge bases inbuilt in the speech analytics solutions, a front-office can achieve higher first call resolution and increased level of sales.

It is certainly possible with most of the speech recognition and analytics services to review call transcripts after the conversations have already taken place. But the output will be more meaningful if an issue is appropriately addressed while the speakers are still on the phone and not once a customer has already hung up and chosen a competitor’s product. Overall, the implementation of the real-time speech recognition and analytics solutions helps companies to ensure clients’ satisfaction and in the long term minimize their attrition.

2. How Accurate Will Be the Extracted Data?

Choosing a speech analytics solution for your business, make sure that it performs transcription in an accurate manner. The accuracy, in this case, is assessed based on the Word Error Rate (WER) metric, which entails the estimation of the total number of words, substitutions, deletions, and insertions in the transcribed text in comparison with the reference.

The industry standard WER is 8% as estimated by the veteran Microsoft scientist Xuedong Huang.

In the provided below video, we explain in detail how WER is calculated and give several vivid examples to demonstrate how the speech-to-text transcription is performed in real-time.

Recognizing human speech is certainly not an easy task for digital programs. Not only they have to solve the difficulty of separating the words of speakers from the background noise, they also need to distinguish the speeches of people talking. Another challenge is to identify separate words, what constitutes a serious problem if the system transcribes the speech of a person, who runs all words in one stream. The Donald Trump’s statement provided in the video above serves as an example of such speech.

Similarly, regional accents and dialects can throw off many speech transcription platforms. A high recognition rate in this case can be achieved by means of syntax and semantics analysis, but to carry it out the system has to be trained to work with these categories. In view of this, when choosing a speech recognition system, try to find the one that has blistering brainpower to handle all the language peculiarities.

3. What Insights Does the Speech Analytics Provide?

When looking for a speech analytics tool, choose a solution that will take you beyond the traditional analysis of the calls’ contents and common causes. The ideal speech analysis should produce truly deep and meaningful insights into the accumulated data, exposing the underlying trends and patterns. It is an ultimate advantage if the system also allows the measurement of tone and speech volume. These two features can be used effectively to assess the emotional context of the conversations.

The purchased by your company solution should have another important feature, and that is the ability to combine the extracted insights into something more visually comprehensible than the lengthy mediocre reports. Intelligent speech analytics applications offer a great variety of graphs and presentation formats. Their main purpose is to provide actionable insights, namely those that can be easily interpreted by both high executives and junior staff members and immediately put into action.

4. How Strong Is the Solution’s Power of Search?

Having the information about the calls collected and analyzed is a big step forward. But what you ultimately want to get is an opportunity to manipulate this data, by building queries and categorizing it in accordance to your own requirements. A good solution always offers an opportunity to select several search criteria to get a better understanding of the discovered information. The power of search is, therefore, an important criterion that should not be overlooked when purchasing a speech recognition and analytics solution.

5. How Difficult is it to Integrate the Solution with the Existing System?

For an optimal result, the purchased by your company speech recognition and analytics solution has to be easily integrable with your existing IT infrastructure. Ask your vendor whether he will be able to customize the solution for you. A fully integrated software enables rich user experience and helps to prevent the alternations between several different interfaces, such as the one of the speech analytics tool and the telephony setup in your office.

Even after the system has already been deployed there might arise a need to change some settings. For example, if you wish to expand the system’s dictionary by adding business-specific terms or tune it to allow the recognition of new languages and geography based accents. Thinking ahead, ask your provider already at the purchase stage whether he will be available to improve the system performance for you in the future or whether this can be done at the user level.
