- Enhanced Voice Services (EVS) is a superwideband speech audio coding standard that was developed for VoLTE. It offers up to 20 kHz audio bandwidth and has high robustness to delay jitter and packet losses due to its channel aware coding and improved packet loss concealment. It has been developed in 3GPP and is described in 3GPP TS 26.441. The application areas of EVS consist of improved telephony and teleconferencing, audiovisual conferencing services, and streaming audio. Source code of both decoder and encoder in ANSI C is available as 3GPP TS 26.442 and is being updated regularly. Samsung uses the term HD+ when doing a call using EVS. (en)
- Enhanced Voice Services (EVS) は、携帯電話の音声通話で、音声をデジタル化する際に用いられる音声符号化方式（音声コーデック）の一種。VoLTE方式の音声通話で使われる上級の符号化方式で、3G音声通話で使用されるAMRや、VoLTEで使用されるAMR-WB (G.722.2) よりも、伝送できる音声周波数帯域が広いため、より高い音を伝送でき、こもったような音声になりにくいなど、クリアな音声を実現できる。 (ja)
