The speech processing module can be divided into two parts, the first part includes speech compression, voice activity detection and echo cancellation module, which improve speech quality ; the other part includes dtmf and cpt module, which generate and detect some necessary telephony signal in the communication. this thesis is organized as follows
該語音處理模塊由兩部分組成,一方面是對語音的處理,包括語音壓縮模塊、靜音處理模塊和回聲消除模塊,主要為了提高voip的語音質量;另一方面是對電話通信的控制和處理,包括雙音多頻模塊和呼叫進程音模塊,主要為了產生和檢測ip電話通信中一些必須的電話信號。Analysis of and survey on the quality of speech based on vselp coding technology
基於矢量和激勵線性預測編碼技術對話音質量的分析和實測By utilizing the semi - markov model and the network flow model based on rtp, we can ensure the right operations be done in the correct way. finally, the subjective evaluating method mos ( mean opinion score ) and the objective evaluating method dtw ( dynamic time warping ) has been combined to estimate the speech quality
在控管結果的評測方面,本文引入了主客觀評測相融合的話音質量評測方法,通過將改進的mos主觀話音評測方法和基於動態時間規正( dynamictimewarping , dtw )的客觀話音評測方法相結合,給出了較為準確的評測結果。Those communication methods used have advantages and disadvantages in those aspects, such as communication quality, adaptation condition, covering scope, geography environment, construction and working cost, real time quality, etc. in order to make the transport of hydrological information better, this dissertation introduced gsm communication methods in the hydrology telemetric system, using gprs cell - phone, by those mobile communication methods, such as gsm sms, gprs sms, gprs data service, circuit data service, tone channel, etc. this dissertation summarized the constitute of hydrology telemetric system, mobile communication methods, and compared them with those traditional methods
現有的水情遙測通信方式有多種類型,它們在通信質量、適應條件、覆蓋范圍、地理環境、建設成本及運行費用、實時性等方面各有優缺點。為了更好地進行水情信息傳輸,本文提出一種基於gsm通信方式的水情遙測系統,通過使用gprs蜂窩電話,採用gsm短消息、 gprs短消息、 gprs數據業務、電路型數據業務和語音通道等多種移動通信方式,為水情數據的傳輸提供了新的解決途徑。Moreover, recognizing that voice encodedecode functions are being pushed closer to the customer, sage products support 2 - and 4 - wire test access at the network edge
挑戰的話音質量測試工具。此外,由於認識到話音編碼解碼功能越來越接近於用戶,It can satisfy the voip application demand at enterprise level and then performs an adjustment test according the vital factors bringing big affection to the quality of voice, such as voice quality and delay of different encoding styles, packaging capacity and delay, echo cacellation algorithm and digital voice mixture algorithm
此網關能夠滿足企業級的volp應用要求。並在此網關設備上針對對語音質量影響比較大的關鍵性因素進行了調整測試,如各類編碼方式的話音質量與延遲、組包大小與延遲、回聲消除演算法、數字混音演算法等。Meanwhile, the telephone gateway in tetra system is introduced. in further research, the principle of tetra speech coding algorithm ? algebraic codebook excitation linear prediction ( acelp ) is introduced and analysed in detail, which is a advanced codebook excitation linear prediction ( celp ). acelp algorithm replaces the excitation signals with algebraic codebook and uses some technique such as minimizing the mean square error ( mse ) and the analysis - synthesis method to obtain characteristic parameters of speech
同時,介紹tetra系統的市話網關,並在接下來的研究中詳細介紹tetra電話網關中應用到的語音編解碼演算法? ?代數碼本激勵線性預測碼( acelp )的基本原理,它是一種簡化了的碼本激勵線性預測碼( celp ) ,它把激勵信號用代數碼本代替,並且運用了均方誤差最小、分析?合成等技術提取出語音的特徵參數,極大地降低了比特率,而且具有較好的重建語音質量。分享友人
