MANILA, Philippines - Smart Communications Inc., the wireless arm of dominant carrier Philippine Long Distance Telephone Co. (PLDT), is now offering high definition (HD) voice call feature to its mobile phone subscribers that stood at 51 million as of end-June.

Rolando Peña, head of the PLDT-Smart technology group, said in a statement that the feature is initially available in select areas in Makati City and Bonifacio Global City in Taguig.

 “HD Voice uses improved modulation techniques which allow for the transmission and reception of crystal clear audio using the same amount of bandwidth as a regular voice call—all you need is an active 3G connection and you will automatically be able to enjoy this new feature,” Peña stressed.

He pointed out that the feature could be enjoyed by subscribers using smartphones capable of Adaptive Multi-Rate Wideband (AMR-WB) including Smart Netphone 701, the Nokia E7, the Sony Ericsson Xperia Mini, and the Samsung Galaxy Ace.

With the new voice call technology, it would be easier for callers to recognize commonly misheard sounds such as “s” from “f”, “m” from “n”, and “p” from “t”.

“If you and the caller happen to be in areas where our network is HD voice-enabled and if you have an HD voice-capable handset running on 3G, you will be able to hear the difference instantly,” he added.

To check if your phone is AMR-WB-capable, check the specifications of your handset.

 “There is still no better way to convey human emotions than with voice. This shows that our super-charged network not only improves mobile Internet speeds, but call quality as well,” he said.
