为什么不自己录制?因为担心口音问题降低了识别率。

阳光在晴朗的蓝天上闪闪发光,微风吹过树林。鸟儿们唱着甜美的歌,花儿绽放着鲜艳的色彩。这是一个美丽的日子,非常适合在公园野餐。
约翰和玛丽计划了好几个星期的野餐,他们很高兴能一起度过这一天。他们装了一篮子美味的食物,包括三明治、水果和自制甜点。他们还带了一条毯子坐在上面,还有一只飞盘玩。
当他们到达公园时,在一棵大橡树下发现了一个阴凉的地方。他们铺开毯子,准备野餐。他们轮流把飞盘扔来扔去,笑着享受着彼此的陪伴。
当太阳开始落山时,他们收拾好东西,开始走回自己的车。他们度过了美好的一天,他们迫不及待地想一起计划下一次冒险。

The sun was shining brightly in the clear blue sky, as a gentle breeze blew through the trees. The birds were singing their sweet songs, and the flowers were blooming with vibrant colors. It was a beautiful day, perfect for a picnic in the park.
John and Mary had planned the picnic for weeks, and they were excited to spend the day together. They packed a basket full of delicious food, including sandwiches, fruits, and homemade desserts. They also brought a blanket to sit on, as well as a Frisbee to play with.
As they arrived at the park, they found a shady spot under a large oak tree. They spread out the blanket and set up their picnic. They took turns throwing the Frisbee back and forth, laughing and enjoying each other's company.
As the sun began to set, they packed up their things and started walking back to their car. They had had a wonderful day, and they couldn't wait to plan their next adventure together.

测评结果

中文识别转换为繁体字,其次在断句方面较精准。

英文识别非常精准,且断句也非常准确。

Whisper 对背景音处理非常好,不管是在有无人声背景音情况下,识别都很准确。

不过字体准确性还有待提高,识别后需仔细检查是否有错别字!
