ETSI ETSI TS 126 177 V14.0.0 (2017-04)53GPP TS 26.177 version 14.0.0 Release 141 Scope The present document specifies the digital test sequences for the DSR Extended Advanced Front-end speech codec. These sequences can be used to test
20、 for a bit exact implementation of the DSR Advanced Front-end codec and quantization (3GPP TS 26.243). 2 References The following documents contain provisions, which through reference in this text, constitute provisions of the present document. References are either specific (identified by date of p
21、ublication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies.

26、anced Front-end ETSI ETSI TS 126 177 V14.0.0 (2017-04)63GPP TS 26.177 version 14.0.0 Release 144 General Digital test sequences are provided to test for a bit exact implementation of the Distributed Speech Recognition Extended Advanced Front-end (3GPP TS 26.243 1). The test sequences may also be use
27、d to verify installations of the ANSI C code in 3GPP TS 26.243 1. Clause 5 describes the format of the files, which contain the digital test sequences. 5 Test sequence format This clause provides information on the format of the digital test sequences for the DSR Extended Advanced Front-end (TS 26.2
28、43 1). 5.1 File format The test sequence files in PC (little-endian) byte order are provided in archive files (ZIP format), which accompany the present document. Following decompression, three types of file are provided: *.inp - Input to the speech encoder. *.cep Cepstral output of the encoder, inpu
29、t to the quantizer. *.pitch Pitch output of the encoder, input to the quantizer. *.class Class output of the encoder, input to the quantizer. *.vad VAD output of the encoder, input to the quantizer. *.bs Output of the quantizer Two test scripts are provided for exercising the Extended Advanced Front
30、-end and quantizer functions. All file formats are described in 3GPP TS 26.243 1. 6 DSR test sequences Forty-three encoder input sequences are provided, 22 with 8kHz sampling, 23 with 16kHz sampling. 8kHz sampling: T00.INP - T21.INP as described in the AMR test sequences document TS 26.074 4. 16kHz
31、sampling: T00.INP - T22.INP as described in the AMR WB test sequences document TS 26.174 5.
