A Clear-Sounding Voice: The Key Factor in Language Learning

Since a large chunk of online learners use their laptops or tablets to take their language classes, the effectiveness of laptop/tablet speakers in delivering the type of clear-sounding audio that is needed must come under scrutiny. What a detailed look into the matter shows is that laptops and tablets feature major deficiencies in terms of sound, as their embedded speakers are both compact to an extreme and usually placed at the rear of the device with the sound oriented away from the user. This type of audio output is sure to dampen the ability of the learner to hear clearly and, as a result, learn effectively.

Speakers designed for music tend to utilize a single full-range speaker unit to handle both high and low frequencies. With the same speaker unit handling both, any tweaks to enhance low-end sound, as is common with music speakers, will by default sacrifice the high-end sounds. This in turn will impair the speaker’s ability to faithfully reproduce all types of voices, as female voices tend to occupy the high frequency range, while male voices are usually in the low frequency range. These issues are even more pronounced with portable Bluetooth speakers where the underlying mechanics and the resulting performance are further limited due to their form factors and aesthetics. What this all means is that for those who are serious about ensuring the best possible conditions for online learning, as opposed to simple edutainment, the best bet is to consider purchasing a speaker specifically engineered for language education.

The treVolo Voice Engine utilized by the BenQ treVolo U Desktop Dialogue Speaker consists of an assortment of unique technologies that enhance the sound of vocals and preserve the minutiae of speech. With its Voice Engine there is no need to increase treVolo U’s volume just to hear the instructor clearly, you’ll be able to listen and communicate effectively with accurate audio that is both clear-sounding and smooth to the ear. Here are some of the points that make the treVolo Voice Engine so unique: • The treVolo Voice Engine automatically cancels low-end noise for frequencies under 100Hz to keep the vocals at their clearest and most authentic while minimizing sound interference during use. • The treVolo Voice Engine was developed using a huge databank of over 200 different vocal samples to create and compare its sound profile so that the frequencies of both male and female speech were taken into account in order to ensure that the full spectrum of human voices can be authentically depicted. • Through its acoustic technology the audio output by the treVolo Voice Engine is fine tuned to encompass hard-to-replicate sounds such as the previously mentioned intonations, aspirations, trills, and consonants so that all aspects of speech are captured. This then allows the learner to hear things clearly and catch all the details so that they won’t have any issues when attempting to imitate the words from their instructor.

By designing the speaker with a 12-degree angle of elevation, treVolo U Desktop Dialogue Speaker ensures that its audio is aimed directly at the listener from an orientation that will give the teacher’s voice much more of a person-to-person feel.

treVolo U is powered by a two-way speaker with dual drivers that are able to accurately cover the full range of vocal frequencies from the high frequency range of female voices (typically about 165hz) to the lower range of male voices (typically around 85hz). Furthermore, the wide frequency range of its two-way speaker makes it so that all the sounds that natural speech encompasses can be clearly heard.
