Telstra goes HD for voice calls

The telco has introduced HD calling for compatible mobiles across its Next G Network

Telstra (ASX:TLS) has introduced high definition voice calling made between compatible phone across its Next G Network.

HD Voice improves voice quality, suppresses background noise and customers calling on HD- compatible phones will not be subject to higher costs for the service.

Telstra Networks and Access Technologies, executive director, Mike Wright, said the difference between a standard and HD call is the voice equivalent of comparing a VHS with a blue-ray DVD.

“HD Voice calling sounds like you’re talking face to face, even if you are hundreds or thousands of kilometres apart,” he said in a statement.

“In addition to the clarity of the calls, the noise suppression features make your HD-compatible handset much more effective in noisy environments such as on the train, in crowded places or in heavy traffic.”

The service is enabled using technology called Wideband Adaptive Multi-Rate coding (WB-AMR). Using a wider dynamic range means over twice the range of voice frequencies are transmitted allowing customers to hear the full range of a person’s voice and makes it much clearer to distinguish between similar sounds.

“HD-voice calls will require the caller and receiver to be using compatible handsets on the Telstra Next G mobile network for the full benefits of the technology.”

The HD service follows the telco’s move to boost its prepaid text and data quotas, replacing its 1c Text+ service with the new Text and Data offering.

Under the change, the telco has removed of the daily limit of 100 1c texts per day and increased data quotas offering from between 500 Megabytes (MB) to 3 Gigabytes (GB). Bonus texts have also been increased (these are used before the customer can send 1c texts), with the $40 plan receiving double the amount previously, and the $50 and $60 plans being upgraded to “unlimited” text to Australian numbers. However, the shift has resulted in an increase in call connection fees and SMS costs.
