From 800acd45ff554dd63f8de365e111c625c8923be6 Mon Sep 17 00:00:00 2001 From: baicai-1145 <3423714059@qq.com> Date: Sat, 7 Mar 2026 05:47:22 +0800 Subject: [PATCH 1/6] Enhance G2P processing by implementing batch input handling in _g2p function, improving efficiency. Update prepare_onnx_input to utilize caching for tokenization and add optional parameters for character ID mapping and phoneme masks. Refactor G2PWOnnxConverter to streamline model loading and configuration management. --- GPT_SoVITS/text/chinese2.py | 17 ++- GPT_SoVITS/text/g2pw/dataset.py | 107 ++++++++++++++---- GPT_SoVITS/text/g2pw/onnx_api.py | 181 +++++++++++++++++++++++-------- 3 files changed, 233 insertions(+), 72 deletions(-) diff --git a/GPT_SoVITS/text/chinese2.py b/GPT_SoVITS/text/chinese2.py index dcce0d96..acfebfe2 100644 --- a/GPT_SoVITS/text/chinese2.py +++ b/GPT_SoVITS/text/chinese2.py @@ -180,10 +180,15 @@ def _merge_erhua(initials: list[str], finals: list[str], word: str, pos: str) -> def _g2p(segments): phones_list = [] word2ph = [] -

845b181360b5c5f4a5ed827ca01cfd5dfd8f58b1 Mon Sep 17 00:00:00 2001 From: baicai-1145 <3423714059@qq.com> Date: Mon, 9 Mar 2026 05:19:28 +0800 Subject: [PATCH 6/6] Implement batch processing for BERT and reference semantic tasks in TTS. Introduce StageLimiter for managing concurrent processing and enhance the TTS class with new methods for handling audio and semantic extraction. Update profiling metrics for better performance tracking during inference. --- GPT_SoVITS/TTS_infer_pack/TTS.py | 261 ++++++++++++++--- GPT_SoVITS/TTS_infer_pack/TextPreprocessor.py | 259 +++++++++++------ .../prepare_bert_batch_worker.py | 197 +++++++++++++ .../prepare_ref_semantic_batch_worker.py | 262 ++++++++++++++++++ GPT_SoVITS/TTS_infer_pack/t2s_scheduler.py | 121 ++++++-- api_v3.py | 64 ++++- 6 files changed, 1024 insertions(+), 140 deletions(-) create mode 100644 GPT_SoVITS/TTS_infer_pack/prepare_bert_batch_worker.py create mode 100644 GPT_SoVITS/TTS_infer_pack/prepare_ref_semantic_batch_worker.py diff --git a/GPT_SoVITS/TTS_infer_pack/TTS.py b/GPT_SoVITS/TTS_infer_pack/TTS.py index 2fd0df35..9c259662 100644 --- a/GPT_SoVITS/TTS_infer_pack/TTS.py +++ b/GPT_SoVITS/TTS_infer_pack/TTS.py @@ -5,6 +5,7 @@ import random import sys import time import traceback +from concurrent.futures import ThreadPoolExecutor from copy import deepcopy import torchaudio @@ -33,7 +34,12 @@ from transformers import AutoModelForMaskedLM, AutoTokenizer from tools.audio_sr import AP_BWE from tools.i18n.i18n import I18nAuto, scan_language_list from TTS_infer_pack.text_segmentation_method import splits -from TTS_infer_pack.TextPreprocessor import TextPreprocessor +from TTS_infer_pack.TextPreprocessor import TextPreprocessor, StageLimiter +from TTS_infer_pack.prepare_bert_batch_worker import PrepareBertBatchWorker +from TTS_infer_pack.prepare_ref_semantic_batch_worker import ( + PrepareRefSemanticBatchWorker, + prepare_prompt_semantic_wav16k, +) from sv import SV resample_transform_dict = {} @@ -442,11 +448,56 @@ class TTS: "upsample_rate": None, "overlapped_len": None, } + self.prepare_bert_stage_limiter = StageLimiter(int(os.environ.get("GPTSOVITS_PREPARE_BERT_SLOTS", "1"))) + self.prepare_ref_audio_stage_limiter = StageLimiter(int(os.environ.get("GPTSOVITS_PREPARE_REF_SLOTS", "2"))) + self.prepare_bert_batch_worker = None + self.prepare_ref_semantic_batch_worker = None + default_text_cpu_workers = 16 + self.prepare_text_cpu_workers = max( + 0, + int(os.environ.get("GPTSOVITS_PREPARE_TEXT_CPU_WORKERS", str(default_text_cpu_workers))), + ) + self.prepare_text_cpu_executor = None + if self.prepare_text_cpu_workers > 0: + self.prepare_text_cpu_executor = ThreadPoolExecutor( + max_workers=self.prepare_text_cpu_workers, + thread_name_prefix="prepare-text-cpu", + ) self._init_models() + if os.environ.get("GPTSOVITS_PREPARE_BERT_BATCHING", "1") != "0": + self.prepare_bert_batch_worker = PrepareBertBatchWorker( + bert_model=self.bert_model, + tokenizer=self.bert_tokenizer, + device=self.configs.device, + stage_limiter=self.prepare_bert_stage_limiter, + batch_window_ms=int(os.environ.get("GPTSOVITS_PREPARE_BERT_BATCH_WINDOW_MS", "5")), + max_batch_items=int(os.environ.get("GPTSOVITS_PREPARE_BERT_BATCH_MAX_ITEMS", "16")), + max_batch_tokens=int(os.environ.get("GPTSOVITS_PREPARE_BERT_BATCH_MAX_TOKENS", "4096")), + ) + if os.environ.get("GPTSOVITS_PREPARE_REF_BATCHING", "0") != "0": + ref_max_batch_samples = os.environ.get("GPTSOVITS_PREPARE_REF_BATCH_MAX_SAMPLES") + if ref_max_batch_samples is None: + ref_max_batch_samples = os.environ.get("GPTSOVITS_PREPARE_REF_BATCH_MAX_FRAMES", "960000") + self.prepare_ref_semantic_batch_worker = PrepareRefSemanticBatchWorker( + ssl_model=self.cnhuhbert_model, + vits_model=self.vits_model, + device=self.configs.device, + is_half=self.configs.is_half, + zero_wav_samples=int(self.configs.sampling_rate * 0.3), + stage_limiter=self.prepare_ref_audio_stage_limiter, + batch_window_ms=int(os.environ.get("GPTSOVITS_PREPARE_REF_BATCH_WINDOW_MS", "5")), + max_batch_items=int(os.environ.get("GPTSOVITS_PREPARE_REF_BATCH_MAX_ITEMS", "8")), + max_batch_samples=int(ref_max_batch_samples), + ) + self.text_preprocessor: TextPreprocessor = TextPreprocessor( - self.bert_model, self.bert_tokenizer, self.configs.device + self.bert_model, + self.bert_tokenizer, + self.configs.device, + bert_stage_limiter=self.prepare_bert_stage_limiter, + bert_batch_worker=self.prepare_bert_batch_worker, ) self.prompt_cache: dict = { @@ -755,47 +806,52 @@ class TTS: Args: ref_audio_path: str, the path of the reference audio.
