Speex: A free codec for free speech
https://speex.org/comparison/
Speex Speex supports intensity stereo encoding and 32 kHz sampling iLBC iLBC frames are encoded completely independently; while this provides better quality when 10% (or more) of the packets are being dropped, this makes the codec suboptimal for clean line conditions.

SPEEX is a free audio codec. good sound quality for speech encoding and decoding. Before introducing all the Speex features, here are some con cepts in speech coding that help better understand the rest of the manual. Although some are general concepts in speech/audio processing, others are specific to Speex.

Speex is a free audio codec which provides high level of compression with good sound quality for speech encoding and decoding. Speex is an open source and patent-free audio compression format designed for speech. Speex is based on CELP (Code-Excited Linear Prediction) and is designed to compress voice at bitrates ranging from 2 to 44 kbps.
Speex (in ios) really poor quality (and robotic) sound
https://stackoverflow.com/questions/12621500/speex-in-ios-really-poor-quality-and-robotic-sound
I'm trying to encode/decode with speex, when I do not, the audio is loud and clear, but when I encode/decode to test audio quality, I get a really poor audio quality and a robotic sound. Here's my init audio method :

Speex Audio Codec, Version 1.2. Description. Speech codec designed for packet networks and voice over IP (VoIP) applications but not for mobile phones. File-based compression is also supported. The flexible codec is based on Code Excited Linear Prediction (CELP) and supports a wide range of speech quality and bit-rates.

It has many quality/speed options you can use by adding a -number to it. speex-float-10 provides better quality than say speex-float-2 - higher values produce better quality and consume more CPU, lower values have lower quality and consume less CPU. soxr-vhq produces better audio quality than speex-float-10 but it is also more CPU-intensive.
Speex Codec – Speech Compression | Adaptive Digital

Speex is an audio compression format specifically tuned for the reproduction of human speech.It is a flexible speech compression algorithm that can be used in a wide variety of voice applications including Voice Over IP (VoIP). Since Speex was designed for VoIP instead of cell phone use, the codec must be robust to lost packets.
