From 912f6643e24d8b737a9718bdd181c418c0039444 Mon Sep 17 00:00:00 2001 From: fawney19 Date: Fri, 19 Dec 2025 09:51:09 +0800 Subject: [PATCH] tune: adjust stream smoothing parameters for better user experience - Increase chunk size from 5 to 20 characters for fewer delays - Reduce min delay from 15ms to 8ms for faster playback - Reduce max delay from 24ms to 15ms for better responsiveness - Adjust text thresholds to better differentiate content types - Apply parameter tuning to both StreamProcessor and _LightweightSmoother --- src/api/handlers/base/stream_processor.py | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) diff --git a/src/api/handlers/base/stream_processor.py b/src/api/handlers/base/stream_processor.py index dddfd4a..07fbe42 100644 --- a/src/api/handlers/base/stream_processor.py +++ b/src/api/handlers/base/stream_processor.py @@ -48,11 +48,11 @@ class StreamProcessor: """ # 平滑输出参数 - CHUNK_SIZE = 5 # 长文本每块字符数 - MIN_DELAY_MS = 15 # 长文本延迟（毫秒） - MAX_DELAY_MS = 24 # 短文本延迟（毫秒） - SHORT_TEXT_THRESHOLD = 10 # 短文本阈值（逐字符输出） - LONG_TEXT_THRESHOLD = 50 # 长文本阈值（按块输出） + CHUNK_SIZE = 20 # 每块字符数 + MIN_DELAY_MS = 8 # 长文本延迟（毫秒） + MAX_DELAY_MS = 15 # 短文本延迟（毫秒） + SHORT_TEXT_THRESHOLD = 20 # 短文本阈值 + LONG_TEXT_THRESHOLD = 100 # 长文本阈值 def __init__( self, @@ -688,11 +688,11 @@ class _LightweightSmoother: 只包含平滑输出所需的最小逻辑，不依赖 StreamProcessor 的其他功能。 """ - CHUNK_SIZE = 5 - MIN_DELAY_MS = 15 - MAX_DELAY_MS = 24 - SHORT_TEXT_THRESHOLD = 10 - LONG_TEXT_THRESHOLD = 50 + CHUNK_SIZE = 20 + MIN_DELAY_MS = 8 + MAX_DELAY_MS = 15 + SHORT_TEXT_THRESHOLD = 20 + LONG_TEXT_THRESHOLD = 100 def __init__(self) -> None: self._extractors: dict[str, ContentExtractor] = {}
